Production process of recyclable packaging bags

Recyclable plastic packaging bags are widely used by the public and provide great convenience in their daily lives, whether it is to buy groceries at the market, shop at the supermarket, or buy clothes, jewelry, and other items. Although reusable bags have become popular, many friends know nothing about their production process. So, what is the production process of recyclable bags? Here's an introduction by the editor:

Recyclable bag production process:

1. Raw materials

Choose appropriate raw materials for the packaging bag and determine the material used to be safe and environmentally friendly.

2. Printing

Printing refers to the process of making a printing plate of the text and image on the original manuscript, then coating the printing plate with ink, and transferring the text and image onto the surface of the printed material through pressure, thus accurately and replicating the same printed product as the original. In general, printing is mainly divided into surface printing and lining printing.

3. Composite

The basic process of recyclable composite soft packaging bags: Since each material has different advantages, two or more materials are bonded together through a medium (such as glue) to make the packaging film or bag reach a better performance of the technology. This technology is called the "composite process" in the production process.

4. Curing

The purpose of curing is to accelerate the solidification speed of the glue between the materials.

5. Slitting

Cut the printed and composite materials into the required specifications for customers.

6. Bag making

The processed materials are made into various styles of bags according to customer requirements. Multiple bag types can be made, such as center-seal bags, side-seal bags, upright bags, K-style bags, four-side-seal bags, or zipper bags.

7. Quality inspection

The quality inspection of the packaging bag mainly includes pre-shipment inspection of raw materials, online inspection of products, and pre-shipment inspection of products.

The above is the entire production process of recyclable packaging bags. However, due to differences in the technology of bag manufacturers, there may be some differences in a specific production step. Therefore, specific situations should still be based on the actual situation of the manufacturer.
