     Food packaging bags are closely related to our lives. With the rapid development of society, the demand for food packaging bags is increasing and there are more and more types. What issues should we pay attention to when choosing food packaging bags?

     1. The packaging of plastic packaging bags for food needs to be marked in Chinese with the factory name, factory address, product name, and clearly marked with the words "food". All products must be accompanied by a product inspection certificate after leaving the factory.

     2. Plastic packaging bags for food have no peculiar smell when they leave the factory. Plastic packaging bags with special smell cannot be used for food packaging.

     3. Colored plastic packaging bags (dark red or black currently used on the market) cannot be used for food packaging, because such plastic packaging bags are usually made of recycled plastic.

     4. Try to choose uncoated or electroplated materials. In modern packaging design, in order to make the packaging more beautiful and corrosion-resistant, a large number of coating materials are used. This not only makes it difficult to recycle materials after the product is scrapped, but also greatly Some of the coatings themselves are toxic, and eating these packaged foods is very harmful to people's health.

     5. Plastic packaging bags for food are not easy to decompose and will cause environmental pollution. It is best to choose green packaging materials when purchasing food. Paper is currently the most widely used green packaging material. Therefore, when purchasing food, choose original paper packaging and biodegradable plastics.

     6.Materials

     The choice of materials to package food depends on the nature of the product itself. For example, packaging of moon cakes requires high barrier materials, packaging of oily foods requires oiled PE. There are many composite materials in material packaging. Choose according to the functional characteristics of the product. This is a customized food packaging bag The important point is that only by choosing the right materials can the shelf life of food be effectively extended.

     7.Design

     There are many designs of food packaging bags, and there are new designs every day. From the appearance, the common food packaging bags mainly include flat bags, edge-sealed bags, stand-up bags, zipper bags, pronged ear bags, sling bags, waist hole bags, T-shirt bags, self-adhesive bags, spout bags, special-shaped bags, etc. How to choose the design of the packaging bag is directly related to the nature of the product and the customer's usage habits.

     8. Pattern

     If your product has unique symbols and charm, you need to design a unique printing pattern for your packaging bag. Beautiful printing images can attract customers' attention, increase customers' purchase expectations, and better highlight the brand image. How to design Producing beautiful prints requires your design team to be strong enough.

     In the 21st century, with the improvement of people's living standards, in addition to improving the quality requirements of the products themselves, the requirements for product packaging are also getting higher and higher. Product packaging is not only required to be beautiful, economical and practical, but also to meet environmental protection requirements.
