Thickness is the plastic packaging bag production process around the problem. But the overall thickness of plastic packaging bag is small, it is difficult to distinguish the naked eye, food manufacturers often difficult to say what thickness they need packaging. Therefore, today giant packaging for you to analyze the thickness of common plastic packaging bags.
First, common thickness
The thickness of plastic bags is generally measured in silk, with 1 mm =100 silk. The state stipulates that the production, sale and use of plastic shopping bags with a thickness less than 0.025 mm are prohibited nationwide. Above this thickness are called eco-friendly shopping bags, and below this thickness are called "thin bags" or "ultra-thin bags." Our daily use of composite bags, the thickness of the general 5-20 silk, belongs to the scope of environmental protection shopping bags.
1, ordinary thin bag: double bag wall of the total thickness of 5 silk commonly known as "thin", agricultural use of plastic film, the general thickness of 5 silk below;
2, thick bag: the total thickness of the double bag wall between 6 silk - 10 silk is "thick", we live in the convenience store used in the small size vest handbag double-sided thickness of 8 silk;
3, thickened bag: the total thickness of the double bag wall is 10-19 silk "thickened", the vest handbag used by supermarkets is generally 12 silk, and the sling handbag sent by ordinary shopping is more than 14 silk.
4. Extra thick bag: the total thickness of the double bag wall is "extra thick". Some vacuum packed cooked food bags can reach more than 20 silk.

Suitable for the thickness of the product is the best, packaging bag thickness has the corresponding performance, emphasis, different food also have the strength of the need, too thick packaging for some products, is a waste.
Secondly, the thickness of the composite plastic bag depends on the final thickness of the bag, because the composite plastic bag has several layers of film to composite, some plastic bags also composite cattle quality or non-woven material, so the thickness of the bag can not only look at the thickness of one of the materials.
Finally, if you are not sure of the packaging bag thickness required by your own products, it is recommended to consult professional packaging bag manufacturers. They have rich experience and professional judgment on how much thickness various products need. The customer only needs to provide the product type, specifications, requirements, etc., and the manufacturer can estimate the thickness range.
