Self-supporting zipper bag manufacturers: the choice of plastic packaging bags need to pay attention to matters
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 problems should be paid attention to when choosing food packaging bags?
1. The packaging of plastic packaging bags for food needs to be marked in Chinese, with the name of the factory, address, product name, and clearly marked with the words for food. All products are accompanied by product inspection certificates after leaving the factory.
Plastic packaging bags for food have no peculiar smell when they leave the factory, and 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, which not only brings difficulties to the recycling of materials after the product is scrapped, but also most of the coatings themselves are toxic, and people eat these packaged foods are very harmful to people's health.
5. Food plastic packaging bags are not easy to decompose, which will cause environmental pollution. A good choice for food is green packaging materials. Paper is currently widely used green packaging materials. Therefore, when buying food, choose raw paper packaging and biodegradable plastics.
6. MATERIALS
What material to choose for packaging food depends on the nature of the product itself. For example, packaging moon cakes requires high barrier materials, packaging oily food requires oil PE, and there are many composite materials in the material packaging. Choose according to the functional characteristics of the product. This is an important point for customized food packaging bags. Only by choosing appropriate 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 point of view, common food packaging bags mainly include flat bags, edge bags, upright bags, zipper bags, fork ear bags, sling bags, waist hole bags, vest bags, adhesive bags, suction nozzle bags, special-shaped bags, etc. How to choose the design of packaging bags is directly related to the nature of the product and the usage habits of customers.
8. Pattern
If your product has a unique symbol and charm, you need to design a unique printing pattern for your packaging bag. Exquisite printing images can attract customers' attention, increase customers' purchase expectations, and better highlight the brand image. How to design a beautiful printing pattern requires your design team to have sufficient strength.
In the 21st century, with the improvement of people's living standards, in addition to improving the quality requirements of the goods themselves, the requirements for commodity packaging are also getting higher and higher. It not only requires commodity packaging to be beautiful, economical and practical, but also meets the requirements of environmental protection. Today, we should advocate green packaging.
