Automatic high-speed T-shirt bag making machine (vest bag making machine） is a bag making machine developed for making supermarket shopping bags and vest bags. The equipment mainly uses HDPE, and LDPE tube film as raw materials for printing, sealing and cutting, and bag making. This machine can equip with a plastic film blowing machine. It can complete feeding, back sealing, cutting, punching, and conveying at one time, with a high degree of automation. It is an ideal equipment for the production of vest bags and flat bags.
What is a Vest Bag (T-Shirt Bag)?
The vest bag is also called the T-shirt bag, which is the plastic bag that we often use in our daily shopping. It can be seen in supermarkets, farmers’ markets, convenience stores, etc. There are three types of vest bags, large, medium, and small, as well as medium and large vest bags.

How to Make a Vest Bag?
The production process of vest bags includes film blowing, printing, sealing and bag making, and other processes.
- Blown film. Blown film is a process in which a plastic sample is heated and melted, passed through an extruder base, and then blown into a film. Blown film has special blowing film equipment. Generally speaking, high-density polyethylene or low-density polyethylene can be used for blown film. But high-density polyethylene is durable and resistant to high temperatures. Therefore, many bag manufacturers usually use high-density polyethylene as the raw material to blow the film.
- Printing. This step is necessary if you want to print a pattern on the surface of the plastic bag. Printing quality is affected by factors such as ink, thinner, layout, printing technology, etc.
- Seal and cut bags. The T-shirt bag making machine includes the process of bonding and cutting the blown film. It is usually done using an automated vest bag making machine. The automatic vest bag making machine can complete feeding, back sealing, cutting, punching, and other processes at one time.
