The difference between plastic packaging bags and plastic packaging roll films

The plastic packaging products produced by plastic packaging bag manufacturers are divided into two forms, one is the plastic packaging bag that has been sealed with three sides, and the other is the plastic packaging roll film with a paper tube in the center. So, what are the differences between plastic packaging bags and plastic packaging roll films? These two types of packaging products have their own characteristics and differences, specifically the following:
1. Plastic packaging bags are finished product packaging bags.
The plastic packaging bags produced by the plastic packaging bag manufacturers have been sealed with three sides, and when the customer uses the plastic packaging bag, the product is packed into the plastic packaging bag, and only needs to be sealed again. Some products that need to be vacuumed use vacuum packaging bags, and the work of vacuuming and sealing can be completed on the vacuuming equipment, which is very convenient.

2. Plastic packaging roll film is a semi-finished plastic packaging bag.
Plastic packaging roll film is also called plastic packaging coil, coil, printing roll, etc., but the name is different, in essence, it is the same form of plastic packaging bag. Plastic packaging roll film is a printed composite roll of packaging film, in the printing plant does not carry out the bag making process, this packaging roll film center has a paper tube, the size of the paper tube is fixed, the width is different according to the width of the customized plastic packaging roll film.
When the plastic packaging roll film is delivered to the customer, the customer needs to have its own automatic filling machine, and the plastic packaging roll film completes the whole process of bag making, filling, sealing and coding on the automatic packaging machine.
The MOQ of plastic packaging roll film is calculated according to "kg", and the MOQ of plastic packaging roll film of most plastic packaging bag manufacturers is 300kg, so the number of finished packaging bags of different widths and different thicknesses within the MOQ range may vary a lot, ranging from tens of thousands to hundreds of thousands.
