The answer is bag making machine.
A bag making machine is used to produce various types of packaging bags made from plastic or other materials. It can process materials of different sizes, thicknesses, and specifications. Generally speaking, most bag making machines are used to produce plastic packaging bags. The plastic used as the raw material is not a pure substance—it is made by combining some materials. The main component is a high-molecular polymer (also called synthetic resin). To improve the plastic's performance, different additives, such as fillers, plasticizers, lubricants, stabilizers, and colorants, are also mixed into the polymer. Only by adding these can the plastic achieve the desired performance.

Here, we will classify bag making machines by using two standards:
1. Industry(Application)
2. Bag type/Bag styles
We hope you’ll find the bag making machine you need.
We mainly have 3 application areas:
A food bag making machine is used to process plastic film materials into food packaging bags. Through a series of automated steps—such as feeding, heating, sealing, cutting, and forming, it converts rolled plastic film into various sizes and shapes. This type of machine is widely used in the food packaging industry for packaging snacks, frozen foods, seasonings, candies, baked goods, and so on.
Industrial bag making machine refers to industrial-grade system used to produce bags from different thermoplastic film materials. It can perform automatic feeding, heat sealing, cutting, punching, folding, printing, and other functions. This type of machine is widely used in industries such as logistics, new energy, chemicals, and construction materials. (Although it also overlaps with food and pharmaceutical packaging, we will explain those separately for easier classification.)
Medical bag making machine can produce medical-grade plastic bags, such as sterilization bags, drainage bags, top seal bags and other medical pouches. These machines are capable of handling medical-grade thermoplastic films like PVC, PE, PP, EVA, and TPE, ensuring that the final products meet strict hygiene and safety standards required in the healthcare industry. It is widely used by manufacturers of medical devices and consumables to produce sterile, durable, and leak-proof medical bags for hospitals, clinics, and home healthcare applications.
The following 7 types are the most common bags we've seen in daily life.
3-side seal pouch is sealed on 3 sides, leaving one side open for filling. It offers excellent air-tightness and is commonly used for vacuum packaging. This is one of the most common bag types in everyday food.
Also known as a back seal pouch, this type is sealed along the center of the back of the bag. It is widely used for packaging items such as candies, instant noodles, and dairy products.

Same as the center seal pouch above.
Also called Doypack, this is a soft packaging pouch with a horizontal support structure at the bottom, allowing it to stand up without external support.
The name “Doypack” comes from a patent filed in 1963 by Thimonie. These pouches are usually made from laminated structures like PET/foil/PET/PE and can include oxygen barrier layers to extend shelf life. They are widely used for beverages and condiments.

Also called "gusset bag", quad seal bag is sealed on all four edges. Typically, one large sheet is folded in half and heat-sealed to form the bag, then cut into individual units. This type of bag has a neat appearance and good sealing performance.

Bag-on-roll is a roll of plastic bags connected end-to-end. Each bag can be torn off along a perforated or easy-tear line. These are widely used in supermarkets, fresh markets, and food processing because they are easy to use, space-saving, and suitable for mass usage.

Spout Pouch is a type of flexible packaging that combines the lightweight, space-saving advantages of a pouch with the convenience of a reclosable spout or nozzle. It is typically made from multi-layer laminated plastic films that offer durability, barrier protection (against moisture, oxygen, and light), and the ability to hold liquids or semi-liquids securely.

The following 5 types are are closely related to logistics in our lives, which you may not have realized.
Bag-in-Box (BiB) is a type of packaging that consists of a flexible inner bag (usually made of plastic or metallized film) housed inside an outer rigid box, typically made of corrugated cardboard. The inner bag is equipped with a tap or spout for controlled dispensing. This design is widely used for storing and transporting liquids, semi-liquids, and viscous products.

FIBC bag (Flexible Intermediate Bulk Container) is a large, industrial-grade flexible bulk bag used for storing and transporting dry, flowable materials such as powders, granules, and grains. FIBC bags are also commonly known as bulk bags, super sacks, big bags, or ton bags.

Dunnage Air Bag (also called an inflatable dunnage bag or air bag) is a type of packaging material used in shipping containers, trucks, and rail cars to secure cargo and prevent movement during transit. These bags are inflated with air to fill empty spaces between loads, stabilizing items and reducing the risk of damage from shifting, vibration, or impacts.
