The difference between packing bag and packing film

Plastic packaging products are divided into two forms, one is already sealed three sides of the plastic packaging bag, one is the center with a paper tube plastic packaging roll film, what are the differences?

First, plastic packaging bags are finished packaging bags.

Plastic bag manufacturers have completed the production of plastic bags, which have been sealed three sides. When customers use plastic bags, they only need to seal the products after they are put into plastic bags.

Plastic bag manufacturers generally calculate the minimum order quantity and quotation of plastic bag according to "one", and the payment for goods to you is also calculated according to "number".

Two, plastic packaging roll film is a semi-finished plastic bag.

Plastic packaging roll film is also called plastic packaging roll, roll material, printing roll and so on, but the name is different. The plastic packaging film is the printing composite packaging film into a roll, the printing plant does not carry out the bag-making process.

When the plastic packaging film is delivered to the customer, the customer needs to have an automatic filling machine. The plastic packaging film can complete the whole process of bag making, filling, sealing and coding on the automatic packing machine.
