Dongguan Beite is a large-scale company specializing in the production of food grade composite packaging. It is a professional manufacturer of composite packaging bags. It uses new equipment to produce packaging bags and roll films, providing comprehensive, environmental protection and safety packaging services for the Chinese market.

1. First of all, you should know what kind of material is suitable for your product. If it is food packaging, you must use materials with better barrier property. If it is electronic products such as data line, you can use transparent materials. Good materials are more expensive, of course.

2. Then determine the size, width, height and thickness of your product. If it is a bag with complicated octahedral seal, you need to measure the length of the organ and the length of the bottom organ. If you need vacuum packaging and your product is not sharp (such as chicken feet, chicken wing bones, etc.) that easily pierce the vacuum packaging of food, I suggest that you use a single layer of 7c-8c (C is the thickness list) Bit, 1c = 0.001mm).

3. Then the price of the food vacuum bag can be calculated clearly according to the size and material. The price = [the first material (length * width * thickness * material unit price) + the second material (length * width * thickness * material unit price) + the third material (length * width * thickness * material unit price) + ink consumption price + glue consumption price + labor cost + manufacturer's profit]

For example, I have a composite food packaging bag for chicken feet, which is 26 in length, 35 in width and 14 in thickness. Then I use PA nylon / CPP, the printing area is full of ink, and high temperature sterilization is required. If nylon is 1kg, 100 yuan, CPP is 1kg, 200 yuan, then the price of the whole vacuum bag can be calculated according to the above formula.
If there is a big difference in the price of two bags of similar size and thickness, it is often different in the materials used. If the price of PET / PE and PA / PE is different, the price difference between two bags is relatively large, because the unit price of pet is much cheaper than that of PA. It may also be caused by the difference in the performance of the two bags. The cooking bag with the same thickness is more expensive than the boiled bag, because the ink and glue used in the cooking bag are much better than that of the boiling bag. Of course, the number of bags you order will also affect the price of bags. If you order 200000 bags at a time and 20000 bags at a time, the manufacturer will apportion the fixed material allowance for each production to the cost of each vacuum bag.
Common composite packaging materials are BOPP, pet, PA, Al, CPP, PE, VMPET, VMCPP, BOPP pearlescent film, BOPP extinction film, Kop, rcpp, kpet, PVC.
Therefore, to sum up, the factors affecting the price of a food vacuum packaging bag include material, specification, performance and quantity.
