Simple, minimal Package Designs that I love!

Number 1, 2, 3image above, is a package design for cheap 'value' range food you can get at any markets. (This one particularly is from Morrisons). A lot of people might think that cheap foods will have labels that are very ugly to match the budget of the ingredients. But you're wrong. Very simple one color hand drawn images grabs your attention. Image 4,5 is my FAVORITE. Sainsbury took their product very vintage, and its very minimal. The chocolate package design has brown circles representing chocolate buttons that's spread out. Cornflakes packaging is more minimal. orange dots represents the cornflakes. I also like the Nutella package design.

9 Reasons Why On-Demand Design Services are Game-Changer
In today’s fast-paced business world, having access to on-demand design services can be a game-changer for companies of all sizes. From convenience and flexibility to cost-effectiveness and efficiency, on-demand design services offer a variety of benefits that traditional design agencies or freelancers simply can’t match. In this blog post, we’ll explore 9 reasons why on-demand design services are revolutionizing the way businesses approach their design needs and why you should consider using one for your next project. 1. Get high-quality design work at a lower cost On-demand design services allow you to get high-quality design work at a lower cost, as you only pay for the specific design services that you need. On-demand design services allow you to get professional design work done on an as-needed basis, rather than having to hire a full-time designer or design agency. This can be more efficient, as you can quickly and easily access the design resources you need, without the need to go through the process of hiring and onboarding a new employee or committing to a long-term contract with an agency. Additionally, on-demand services typically have a pool of talented and experienced designers available to work on your project, allowing you to get high-quality design work done quickly and efficiently. 2. Get access to a wider pool of talent With on-demand services, you have access to a wider pool of talent, as you are not limited to designers in your local area. On-demand design services typically have a large pool of designers available to work on projects, as they are not limited to hiring designers who are based in a specific location. This means that you have access to a wider range of talent and can choose the designer who is best suited to your project, rather than being limited to designers who are available in your local area. This can be especially beneficial if you are located in an area with a limited pool of design talent, or if you are looking for a designer with a specific skill set or style that may be difficult to find locally. By working with an on-demand service, you can access a global pool of designers, increasing your chances of finding the perfect fit for your project. 3. Flexibility to create customized solutions On-demand design services offer greater flexibility, as you can work with the designer to create a customized solution that meets your specific needs. On-demand design services allow you to work with a designer on a project-by-project basis, rather than hiring a full-time employee or design firm to handle all of your design needs. This offers greater flexibility because you can tailor the scope of the project to your specific needs and work with the designer to create a customized solution. For example, if you only need a few designs for a marketing campaign, you can work with a designer to create those specific assets, rather than paying for a full-time employee or design firm to handle all of your design needs on an ongoing basis. This can be especially useful for small businesses or organizations that have limited resources and need to be able to scale up or down their design needs as their business grows or changes. On-demand design services can also be more cost-effective because you only pay for the specific services that you need, rather than paying for a full-time employee or design firm to handle all of your design needs on an ongoing basis. This can help you to better control your design budget and allocate your resources more efficiently. 4. Faster turnaround time You can get faster turnaround times with on-demand design services, as you can work with multiple designers in parallel to complete a project more quickly. On-demand design services allow you to work with multiple designers in parallel on a project, which can help to speed up the design process. This is because you can divide the work among multiple designers, rather than relying on a single designer to handle all aspects of the project. This can be especially useful if you have a large project with a tight deadline, as it allows you to get the work done more quickly. For example, if you have a branding project that includes designing a logo, creating a style guide, and designing marketing materials, you can work with multiple designers to complete these tasks in parallel. This can help to reduce the overall turnaround time for the project and get it completed more quickly. Working with multiple designers in parallel can also be beneficial because it allows you to tap into the diverse skills and expertise of different designers. This can help to ensure that you get the best possible results for your project and that all aspects of the project are completed to a high standard. 5. Greater scalability On-demand design services offer greater scalability, as you can easily increase or decrease the amount of design work that you need on a project-by-project basis.

Technical data sheet: properties and parameters of plasic resin
https://baobikhangloi.com.vn/bang-du-lieu-ky-thuat-cac-dac-tinh-va-thong-so-cua-hat-nhua 1. Melt Flow Index (MFI) Melt Flow Index (MFI) or also known as flow rate - Melt Flow Rate (MFR) is a measure of the ability of molten plastic to move under a specific pressure. This is an important, regularly tested metric as they tell us and control the flow of molten plastic from the tank through the screw to the blow mold, die, injection molding head or any other parts that have any other shaping function. MFI is inversely proportional to the viscosity of the resin. Low MFI means high viscosity materials, they flow with greater resistance and hence slower than low viscosity materials. The MFI can be the only indicator on the technical data sheet that has no specific value that can vary significantly from batch to batch with the same resin code. This is because polymer copolymerization is unlikely to take place precisely at the molecular level. The length of the polymer chains affects the average molecular weight and viscosity of the finished product, and changes the MFI. In many cases, MFI index is the criterion to evaluate the quality of a batch produced on the same type of plastic resin and manufacturer. The MFI index tells us which materials are suitable for which type and treatment method in the manufacturing industry. Injection molding machines, blow extruders tend to be suitable for materials with high flow rates (low viscosity). The extruder is compatible with low flow rate (high viscosity) materials. Strict control of the MFI value of input materials is important to the productivity and quality of the product. The MFI number exceeds the normal level, causing the plastic to be pushed out too quickly, and if it is too low, will cause the plastic to flow out too slowly. In all cases, other parameters on the mechanical system are affected. There are two methods of measuring plastic flow, automatic or manual, based on ASTM D1238 or ISO 1133 test standards. The manual measurement process, temporarily called process A, is useful for organizations whom do occasional testing, using a variety of materials in order to find a better and more suitable material for their production of plastic products job. Process B, on the other hand, is an automated process, ideal for organizations that repeatedly test the same material under different conditions, to find the correct value for scientific purposes. Theoretically, both methods, if properly implemented, should give identical test results. The range of factors that can affect MFI flow index test results is very wide. For accurate results, it is necessary to be aware of each problem, strictly follow the equipment inspection and maintenance procedures. The plastometer machine used in the test is constructed of a temperature-controlled cylindrical material tank. The resin introduced into this tube, after being melted, is forced to flow through a capillary tube with a diameter of 2,095 mm at the bottom of the barrel, under the pressure of a piston actuated by a standard weight. The mass of molten plastic in grams that flows through the capillary in 10 minutes is the MFI of the material. There is also a slight difference between standards ASTM D1238 and ISO 1133. But they perform essentially the same function, and the manufacturers consider them to be technically equivalent. ASTM D1238 is the test method for measuring MFI flow rates for thermoplastics expressed in units of grams/10 minutes. And ISO 1133 standard defines volumetric melt rate (MVR) in cm3/ 10 minutes The melt volume (MVR) obtained in the ISO 1133 test, multiplied by the melt density gives the MFI. However, it should be noted that the density when melted plastic is not the same as the density of the material under normal conditions. For example, Polypropylene has a specific density of 0.91 grams/cm3 but their melting density is only 0.70 grams/cm3. Applying the density or density value under normal conditions to calculate the MFI with the MVR value gives misleading results.
Criteria for choosing plastic packaging from the manufacturer's perspective
https://baobikhangloi.com.vn/tieu-chi-lua-chon-bao-bi-nhua-duoi-goc-nhin-cua-nha-san-xuat 1. What plastic material will be suitable for your packaging? To determine the material, let's take a look at the characteristics of each of the major resins commonly used. Polyethylene (PE) packaging is the most basic in terms of both production process and appearance. They are cheap and easy to manufacture, and therefore occupy a large market share, appearing in all supply chains to retail chains. PE plastic is divided into HDPE or LDPE (high density and low density). HDPE bags are hard and strong, have more opacity than LDPE. LDPE plastic bags are more resilient and can be stretched than HDPE. Bags made of PP (Polypropylene) or OPP (Orient-Polypropylene) are much harder and transparent than PE, but they are also very easy to tear when there is a puncture or scratch. In addition to the type of plastic, customers can also decide to use virgin plastic or recycled plastic, mixed with a certain ratio. Usually, to save costs for customers, manufacturers also often recommend that they order bags from recycled polyethylene. However, manufacturers still do not have a unified standard on the mixing ratio and a general assessment of the impact on the durability of recycled bags. Of course, their mechanical properties such as strength and toughness will decrease as the mixing ratio is increased. In addition, they will not look as good as products made of virgin plastic. Even a non-professional can tell with the naked eye that he is holding a bag made of recycled plastic in his hand. Not all manufacturers agree to use recycled plastic in their production processes, especially for food packaging items. This form of cost savings can only be realized when producing packaging for the secondary market. Products made from recycled plastic are often cloudy, gray or dirty beige. People often produce black plastic bags to cover these defects.
How to calculate the weight of a plastic bag when knowing the size and thickness
https://baobikhangloi.com.vn/cach-tinh-can-nang-cua-tui-nhua-khi-biet-kich-thuoc-va-do-day a. What is specific gravity or density? Specific gravity or density is the mass of matter in a given volume, is calculated by dividing the mass of matter by its volume. Here we have the formula: D = m/V, with D (Density) is the density, m is the mass and V is the volume. b. What does the density index mean? The density of a substance helps us to calculate their weight per unit volume, knowing how much heavier one substance is than another based on their density. For example, gasoline has a density of 700 kg/m3, which means that the amount of gasoline contained in a tank with a volume of 1 cubic meter will weigh 700 kg. Iron has a density of 7800 kg/m3, which means that one cubic meter of iron will weigh exactly 7800 kg. All chemical elements known to man have been found to have their densities by measuring and experimenting many times. c. How to calculate the weight of a plastic bag by density We already have the formula for density above, and when we reverse the equation, we can calculate the weight when we know the density and volume. The formula would be: m= D x V Density is given in kilograms per cubic meter (kg/m3) or grams per cubic centimeter (g/cm3). Given the very light weight of plastic packaging, converting to the g/cm3 system will help simplify the formula for calculating their mass. The density (D) of each plastic material can be found easily online, or from your packaging supplier. This parameter is printed on the plastic resins packaging that they use to create the product. For example: The density (D) of POF shrink film is 0.92 g/cm3, LDPE is 0.91 and PVC is 1.4. The volume of the bag will be calculated by length x width x height, and the height here is the thickness of the bag (of both sides of the bag combined). Don't forget to convert the thickness to cm. If the thickness is being measured in mm, divide it by 10, and if it's in microns, divide it by 10000. Let's take an example: the size of LDPE plastic bags is 80 cm x 150 cm x 70 microns, we have the formula for weight calculation as D x V = 0.91 x 80 x 150 x 0.007 = 76.44 grams/ bag. 1 kg is equal to 1000 grams, dividing 1000 by 76.44 we get 13.08. That is, with the above LDPE 80 x 150 cm bag size 70 micron thick, one kilogram will include about 13 bags.. It should be noted that the thickness in this case is for both sides of the bag, which means that each membrane layer of a bag is only 35 microns thick.

Refrigerator Plastic Bag
https://baobikhangloi.com.vn/tui-dong-lanh There are certain types of products that need to be frozen at low temperatures during storage and transportation, such as fruit, meat, fish, etc. And in reality, there is almost only the packaging whith plastic material, is possible to best meet the preservation requirements for these food items, with the lowest cost. However, not any type of plastic can be used. All packaging materials have different properties, advantages and disadvantages, and only by understanding their physical properties as well as their advantages and disadvantages can we choose the right plastic material. For frozen foods, in addition to preventing them from spoiling, preserving the taste and quality of the food is also a mandatory criterion. Currently, there are three main types of flexible plastic packaging used in the frozen food industry The first type is a simple single-layer bag, which can be PA, EVA or LLDPE. This type of bag has the ability to store in medium frozen conditions, often used to store vegetables or products with short storage and transportation times. Their advantage is that they are easy to produce and use, and have the cheapest price compared to the other two types. The second is a composite film packaging, which is a bag that uses glue to combine two or more layers of plastic film material. For example, OPP combined with LLDPE, or PA and LLDPE. This combination gives them better resistance to moisture, cold and puncture. The third is plastic packaging produced by multi-layer extrusion machine. This machine has multiple feed ports and separate extrusion shafts, but all lead to a single blow die head. This structure allows manufacturers to create a multi-layer packaging with different materials without the need for glues or adhesives. They have both durability, high cold resistance but are also safer for food, as they do not have to use chemicals in the production process. Both PA, LLDPE and EVA are low temperature resistant, tear resistant and puncture resistant. Mixing these materials together during co-extrusion or film lamination can greatly improve moisture, oxidation and mechanical strength properties.
What are the special features of vacuum bags, what material are they made of?
https://baobikhangloi.com.vn/tui-hut-chan-khong-mang-ghep-pa-pe Depending on the purpose of packaging, we can use single-layer plastic bags or laminated film packaging (multi-layer) to vacuum. In theory, all types of plastic bags can be vacuumed, as long as they are thick enough to not tear under the strong suction of the vacuum. After the air is sucked out and sealed, the packaging must remain intact so that air does not re-enter the interior. For the purpose of vacuuming for family activities, most types of thick enough plastic bags can meet well. However, in industrial production, the story is completely different. Vacuum bags for frozen foods require the ability to withstand low temperatures for a long time without drying out, a phenomenon that common plastic materials such as LDPE, HDPE or PP all face. As for the purpose of packaging to minimize the volume and volume of packages such as pillowcases, comforters, mattresses, etc., The packaging used needs to be soft and flexible but still has to be strong enough to withstand extreme suction, compressing the product inside to the smallest possible size. High-thickness Low-density Polyethylene (LDPE) bags can meet these packaging requirements. When the vacuum cleaner sucks the air out of the package, it creates wrinkles and shrinks on the package. With stiffer materials such as Polypropylene (PP) or High-density Polyethylene (HDPE), these creases can form tearing folds that lead to packaging failure. Vacuum LDPE bags can also be added to the material tank when being produced, adding a toughness additive to the material tank, which improves packaging performance significantly. Returning to the vacuum-sealed plastic bag for frozen food, manufacturers need to find a material that can withstand strong suction to completely remove the air inside, and can withstand freezing temperatures for a long time. There are many engineering plastics that can meet this requirement, but they have problems with heat sealing. And most importantly, they have not been proven to be safe and approved for food storage according to the standards issued in many countries. Using such packaging would be very unsafe, and the product contained inside would almost no longer have a chance to be exported. And the main solution is a type of laminated film packaging made up of many layers of materials combined to create outstanding properties, with the innermost layer in direct contact with the product being food safe materials (LDPE). and outer layers are engineering plastics with outstanding properties. There are many types of vacuum bags with different compositions such as PET/PE, PA/PE, PE/PA/EVOH, OPET/PP, OPA/PP, etc. There are also bags due to special requirements that are composed of 5, even 7 different layers of film. The selection of the right type of vacuum bag will be based on the needs and responsiveness of each type of material that makes them up. For example, bags made of PA/PE are safe to boil at 100°C, but cannot be sterilized at 121°C, but PA/PP or PET/PP bags can. This is because the melting point of PE is only 120°C and PP is up to 165°C. There is one thing in common among all vacuum bags currently on the market, is that they can all be considered freezer safe, because this is the core purpose of this type of packaging.
