Mylar bag Custom Process

Ewaybag is a professional packaging bag manufacturer; we produce food packing bags, mylar bags, weed bags, coffee bags, packaging bags, stand up pouches, flat bottom bags, zipper bags, and three side seal pouches.
The company’s most significant advantage is that the company has today’s advanced gravure high-speed printing machine, flexographic printing eight-color machine, four-color machine, blow molding machine and a complete set of post-process equipment. Provide customized packaging bag services to meet each customer’s individual needs, including size, color, material, etc.

Customers must provide source files in formats such as AI.PSD.CDR for design and layout. If there is no design draft, they can communicate with our packaging bag manufacturer to offer design ideas, and the information must be carefully checked.
Take food packaging bags as an example: after the specification, material, thickness, and bag type of food packaging bags are determined, enterprise designers or professional design and production teams should make design drawings based on these data. In the design process, reference suggestions should be given, and the bag type should be finally determined.
Particular attention should be paid to the information on the packaging bag, such as manufacturer’s name, ingredients, product introduction, place of origin, net weight, specifications, food label number, QS certification, hygiene license number, production date, storage conditions, shelf life, edible method, manufacturer Name, address, product barcode, and contact number, etc.
After all the details are determined, our professional quotation staff will quote the customer.

After the artwork is determined, professional technicians are required to color-separate the pattern and repair some dark places; simultaneously; it takes more than a dozen processes to complete the plate making.
Generally, composite plastic flexible packaging is a gravure printing process, requiring engraving a copper plate first. The copper plate is engraved according to the pattern and size of the customer’s plastic packaging bag, so once the copper plate is engraved, it is dedicated to the particular bag and cannot be modified. Neither the size nor the surface of the bag can be changed. The price of a set of copper plates is relatively high, so before making plates, customers must be cautious to confirm that the pattern and size will not be wrong.

After the raw materials are ready, the surface film is printed with a high-speed printer. During the printing process, there is a plate cylinder for each color; the engraving of the plate cylinder is concave. We offer digital, plate, and cylinder printing.

The printed surface film and the easily heat-sealable inner film are compounded with a particular high-speed peritoneal machine for special glue;
a plastic packaging bag is made by compounding several layers of movies of different materials, and the compounding process is to combine these. The layers are firmly compounded together. The compounding process should generally be checked first if a plastic packaging bag has a layering phenomenon during use.

After compounding, it needs to be cured in a curing room above 45 degrees for more than 24 hours in order to make the food packaging bag not easy to delaminate.

At this time, the production of food packaging bags has come to an end. The bag-making technicians need to have specific skills. They must ensure that the edges of the color-printed packaging bags are well-sealed and air-tight and have specific technical skills in the temperature control of the hot knife. After inspection by the quality inspector, it leaves the factory; the slitted and reminded roll film is placed on the bag-making machine for bag making. Such as the zipper bag-making machine, which can manufacture self-supporting bags with zippers, eight-side sealing bags, etc.

The main items of packaging bag inspection include specifications (length, width, thickness), appearance, overprint error, color difference, peel strength, heat sealing strength, etc.
Length and width are measured with a ruler, and thickness is measured with a thickness gauge.
The color difference is mainly checked with the standard seal sample, and the color difference at the arm distance should be consistent. In terms of color, Jianhongxing Packaging will also use a 50x magnifying glass to check the printed matter’s color carefully. Generally, paints are made up of dots one after the other. If the color is wrong, the bubbles will appear irregularly distributed.
Overprint errors are mainly checked for double-sided printing by visual inspection.
The AGS-5KG electronic universal testing machine mainly tests peel and heat seal strength. The detection principle is the same as that of the computer tensiometer.

Yes, you can print on mylar bags; now, the technology has reached the point where individuals can publish their mylar bags using printers. Especially inkjet printers, digital printer technology has developed to the point where you can print your custom patterns.

But suppose an individual is to sell custom mylar bags. In that case, we recommend that it is still to mylar bag manufacturers to customize bag manufacturers with professional machines and technology, printing more exquisite patterns. As a professional mylar bag manufacturer, we also provide design services for customers better to reflect their ideas and logos on the mylar bag.

Here is a detailed description:

Types of Printing

Two main types of printing can be used on Mylar bags:

Digital Printing
Digital printing is a process that uses digital technology to transfer an image directly onto the Mylar bag. This type of printing is done using a printer similar to an office printer, but it is designed to print on various materials, including Mylar. Digital printing is a popular option for Mylar bags because it is fast, cost-effective, and allows for high customization.

Flexographic Printing
Flexographic printing is a printing process that uses a flexible printing plate and a rotary printing press. The printing plate is made from rubber or polymer and is mounted onto a cylinder. The ink is then transferred from the printing plate onto the Mylar bag as it passes through the printing press. Flexographic printing is a popular option for printing on Mylar bags because it is fast and can print large quantities quickly.

Printing Considerations

There are a few things to consider when printing on Mylar bags:

Surface Preparation
Before printing on Mylar bags, it is essential to ensure the surface is clean and free of dirt or debris. Any foreign matter on the bag’s exterior can interfere with the printing process and result in a poor-quality print.

Ink Compatibility
Mylar is a synthetic material that is resistant to most types of ink. However, using inks specifically designed for printing on synthetic materials like Mylar is essential. Using the wrong ink can result in smudging, fading, or other printing issues.

Printing Presses
Both digital and flexographic printing presses can be used to print on Mylar bags. It is essential to use a press specifically designed for printing on synthetic materials like Mylar, as this will help ensure the best possible print quality.

Color Matching
Mylar bags can be printed in a wide range of colors, but it is essential to accurately match the design’s colors. This can be challenging, as the colors may appear differently on the Mylar material than they do on a computer screen. Using a color-matching system is an excellent idea to ensure that the colors on the printed Mylar bag match the intended design.

Finishing Options
A few finishing options can be applied to Mylar bags after they have been printed. These options include laminating, die-cutting, and perforating. Laminating adds an extra layer of protection to the printed Mylar bag, while die-cutting and perforating allow the bag to be easily torn or opened.

In conclusion, it is possible to print on Mylar bags using digital or flexographic printing methods. So to ensure the best print quality, it is essential to consider surface preparation, ink compatibility, printing presses, color matching, and finishing options.

Mylar bags effectively protect against moisture and insects.

Mylar bags Introduction:
Mylar bags are a plastic film made from polyethylene terephthalate (PET). They are known for their durability and resistance to punctures and tears, making them a popular choice for storing food and other items that need to be protected from moisture, air, and pests. However, it is essential to consider whether Mylar bags are genuinely resistant to pests, including bugs.

Can Bugs Chew Through Mylar Bags?

In general, Mylar bags are resistant to chewing and biting by pests such as insects. The material is too complex and smooth for most bugs to be able to grip or chew through, and the bags are also sealed tight to prevent pests from getting inside.

However, it is essential to note that some types of pests, such as mice and rats, are capable of chewing through almost any material if they are determined enough. These pests have strong teeth and jaws and can chew through wood, plastic, and even metal if needed. While it is unlikely that they would be able to chew through a Mylar bag, it is possible if the load is thin or if the pest is particularly determined.

Conclusion:
Overall, Mylar bags are reliable for protecting items from pests, including bugs. While some types of problems may be able to chew through the material, it is doubtful, and the bags are generally resistant to chewing and biting by most types of bugs.

20 to 30 years

Available food in the mylar bag can be stored for the most extended 20-30 years; food shelf life is 1-2 years; the specific food in the mylar bag shelf life is not the same.

Moist foods, such as home or commercially canned goods, in mylar packaging, last up to ten years, but storing moisture-rich foods is not recommended due to the increased likelihood of botulism. Dried foods, like beans and grains, can last 20 to 30 years when stored correctly in sealed foil bags.

Food stored in Mylar bags can last a very long time, provided the bags are properly sealed and stored in the right conditions. The exact shelf life of food stored in Mylar bags will depend on several factors, including the type of food, the temperature at which it is stored, and the amount of oxygen in the bag.

Shelf Life of Different Foods in Mylar Bags

Grains and legumes: Grains and legumes, such as rice, beans, and oats, can last for several years when stored in Mylar bags. These foods are relatively dry and low in fat, which makes them less prone to spoilage.

Dried fruits: Dried fruits, such as raisins, apricots, and cranberries, can last for up to 2 years when stored in Mylar bags. These foods are high in sugar and relatively low in moisture, which helps to preserve them.

Nuts: Nuts, such as almonds, peanuts, and cashews, can last up to 2 years when stored in Mylar bags. These foods are high in fat, which can turn rancid over time. To extend their shelf life, keeping them in a cool, dry place is essential.

Jerky: Jerky, a type of dried meat, can last up to 1 year when stored in Mylar bags. Jerky is low in moisture and salt, which helps preserve it.

Factors Affecting Shelf Life

Temperature: The shelf life of food stored in Mylar bags can be significantly affected by temperature. Generally, the lower the temperature at which the food is stored, the longer it will last. For example, food stored at room temperature typically has a shorter shelf life than food stored in a cool, dry place.

Oxygen: Oxygen is another factor affecting the shelf life of food stored in Mylar bags. Oxygen can cause food to spoil by promoting the growth of bacteria and other microorganisms. To reduce the amount of oxygen in the bag, it is important to properly seal it using a vacuum sealer.

Conclusion

Overall, the shelf life of food stored in Mylar bags can vary greatly depending on the type of food, the temperature at which it is stored, and the amount of oxygen in the bag. By following proper storage techniques, you can extend the shelf life of your food and ensure that it stays fresh and safe to eat.

Yes, as leading factory in line of package, of course we can custom make the bag exactly based on your requirement(Style, Size, Printing, etc).

Actually, some FREE samples similar to your request can be provided for checking, Customized sample also available.

Amazon U.S. site released a “Policy update affecting Mylar bag listings” announcement. According to the relevant regulatory requirements, by August 5, 2022, the report shows that all opaque or monochrome Mylar bags must be removed from Amazon stores, or Amazon will remove these ASINs.
Sellers must make a removal request within 30 days of receiving this notice to have their inventory sent to your designated return address.

Information is available to indicate that Amazon is getting rid of Mylar bags. Mylar bags are packaging materials made from a thin layer of plastic called polyethylene terephthalate (PET) or metalized PET film, which is coated with a thin layer of metal, usually aluminum. They are commonly used for storing and preserving food and other purposes such as packaging electronics and other goods.

Mylar bags are popular for protecting the contents from light, moisture, and oxygen, making them suitable for long-term storage. They are also lightweight, durable, and easy to seal, which makes them an attractive packaging option for many businesses and consumers.

Overall, Amazon is getting rid of Mylar bags, but they remain a popular and effective packaging option for many products.

Sure! Here’s a detailed description of how to cut mylar bags :

Preparation:

Gather the necessary tools: a sharp pair of scissors, a ruler or measuring tape, and a mylar bag.

Step 1: Measure and mark the desired size of the mylar bag

  • Using a ruler or measuring tape, measure the desired width and length of the pack.
  • Use a pen or marker to mark the cutting lines on the bag.

Step 2: Cut along the marked lines

  • Place the bag on a flat, stable surface.
  • Using a sharp pair of scissors, carefully cut along the marked lines to create the desired bag size.

Step 3: Remove any excess material

  • If there are any excess edges or corners of the bag, use the scissors to trim them.

Step 4: Check for smooth edges.

Examine the edges of the bag to ensure that they are smooth and even. Use scissors to trim any uneven or frayed edges if necessary.

And that’s it! With these steps, you can easily cut mylar bags to the desired size and shape.

What foods Cannot be stored in Mylar bags?

Foods that Should NOT Be Packaged in Mylar Bag (with an Oxygen Absorber) Brown rice is high in oil and has a short shelf life. 

Moist or damp foods, Highly acidic foods, Whole grains, and Foods high in moisture or oil content, such as 

raisins, nuts, granola, chocolate chips, cookies, and crackers are NOT good candidates for long-term storage in a Mylar bag.

There are a few types of food that should not be stored in Mylar bags:

Moist or damp foods: Mylar bags are not airtight, so they are unsuitable for storing wet or humid foods. These foods can quickly spoil and lead to mold growth, which can contaminate the other foods stored in the same bag.

Highly acidic foods: Foods with a high acid content, such as tomatoes, citrus fruits, and pickles, should not be stored in Mylar bags. The acid in these foods can react with the metal layers in the bags, causing them to break down over time. This can lead to releasing harmful chemicals into the food, which can be dangerous if consumed.

Whole grains: Whole grains, such as rice and oats, can contain small insects called weevils. These insects can lay eggs in the grains, hatching and growing into adult insects. Mylar bags are not thick enough to prevent these insects from getting through and infesting the food stored inside.

Strongly flavored foods: Foods with intense flavors, such as garlic and onions, can easily permeate the walls of Mylar bags and affect the taste of the other foods stored in the same bag. It is best to store these foods in separate, airtight containers to prevent their flavors from affecting the different foods.

Highly perishable foods: Foods that spoil quickly, such as meat, poultry, and fish, should not be stored in Mylar bags for long periods. These foods need to be kept at a consistent, cool temperature to prevent spoilage, and Mylar bags are unsuitable for this purpose. Instead, storing these types of foods in the refrigerator or freezer is best.
