When customizing plastic packaging bags, plastic packaging bag manufacturers generally calculate the MOQ, unit price, printing fee and other data according to the size. Therefore, it is particularly important to accurately determine the size of plastic packaging bags.

As a very common product that is very important to commodities, is there a relatively fixed error value for plastic packaging bags?

1. Width and length error standard:

Bone bag: length and width tolerance is +5/-2mm (PE)

Flat pocket: length and width tolerance is +3/-Omm (PE/PO/PP)

Square bag: height tolerance is 1cm (PE)

Bag along the line: the length and width tolerance is +2.5/-2mm (OPP/PE/PP)

2. The hole position error standard:

Bone bag: The position deviation from the template is within 5mm.

Flat pockets: The position deviation from the template is within 5mm; manual punching is within 10mm.

Therefore, when you customize the plastic packaging bag, the general plastic packaging bag manufacturer will recommend that you leave a certain width and length margin for the bag. The purpose is to avoid the inaccurate size of the plastic packaging bag when there is an error, thus affecting the your use.
