The production process of food plastic bags usually includes the
following steps:
1. Material preparation: Choose plastic materials that meet food
safety standards as raw materials for food plastic bags, such as
polyethylene (PE), polypropylene (PP), polyethylene vinyl acetate
copolymer (EVA), etc. These materials need to be inspected and
screened to ensure their quality and compliance with relevant
regulatory requirements.
2. Printing design: Carry out printing design for food plastic bags
according to customer requirements and product needs. This includes
choosing the appropriate printing method (such as flexographic
printing, letterpress printing, etc.) and colors, as well as
printed patterns, text, brand logos, etc.
3. Bag making and forming: After the prepared plastic sheet is
printed, it enters the bag making and forming process. This step
usually includes operations such as cutting, folding, heat sealing
and crimping. Through heat sealing technology, the edges of the
plastic sheet are heated and pressed together to form the bottom
and sides of the bag.
4. Plastic bag processing: further processing and processing of the
prepared food plastic bags as needed.
This may include adding functional touches such as zipper seals,
bottom closures, opening designs, and
more.
5. Inspection and packaging: Conduct quality inspection on the
prepared food plastic bags to ensure that they meet relevant
standards and requirements. Afterwards, the plastic bags are packed
and packaged in preparation for shipment.
