The Production Process of Flat Bags
The production of biodegradable plastic bags is an interesting process.
Firstly, workers put the raw material of biodegradable bags, called masterbatch, into the accumulator. Then workers manipulate the machine to melt the masterbatch by heating it at a high temperature.
Secondly, the melted raw materials are blown outwards through the extruder into a tube, thus creating the plastic film. The plastic film tube is gradually cooled during the production process and then flattened by a rolling machine. The flattened plastic tube becomes the first appearance of a biodegradable plastic bag, which is thin, soft, and easy to handle.
If you need some patterns, they will be sent through the transfer device for subsequent printing. Ink roller through the pre-set patterns to the film printing, and then onto the roll. The workers will be on the roll of printed film to the sealing and cutting machine for cutting and finally forming our most common biodegradable flat bags.
As for shopping bags, they need a final processing step. Workers will take these cut plastic bags to the press, with the help of the press, these plastic bags one by one will have a handle, and finally these plastic bags will be packaged and shipped.
The type of bag varies a little in the way it is made, but ShinHigh has 20 years of experience in making biodegradable bags so you can leave the design up to us without worries.
Advantages of Flat Top Bags

Each bag has a perforated edge at the top that connects to the bottom seal line of the other bag. So it is easy to tear off and separate them one by one.
Our biodegradable flat-top bags are strong and hard to break. So they are highly resistant to pulling and are not easily punctured.
The bottom and edges of the bag are tightly sealed and do not leak easily. As a result, they can carry heavier loads.
