What is the Biodegradable Bag Making Machine?

A biodegradable bag making machine is specialized equipment that automatically processes biodegradable film rolls to produce finished biodegradable bags. Compostable materials that need to be controlled through temperature in precise manner and sealing technology to maintain the integrity of the biodegradable films are intended for the machine.

The state-of-the-art biodegradable bag making machine features high-level automation system, a servo motor, PLC control, and touch-screen, which guarantee smooth operation and production quality.

Key Features

High-Speed Production

It's used continuously and provides a high production rate for bag manufacturers without compromising their bag quality.

Advanced Servo Control System

By using a servo driven mechanism, the length of the bags is controlled to guarantee an accurate length control, reduce material wastage and improve operational efficiency.

User-Friendly PLC Control Panel

PLC-based control system with touchscreen features eliminates employee operation risks and facilitates easy monitoring and operation of machine functions.

Precision Sealing Technology

The machine provides strong and reliable seals, ensuring the durability and performance of biodegradable bags.

Energy-Efficient Operation

Favoured machine design improves power usage, operation expenses.

Automatic Counting & Stacking

Integrated counting systems and counting and stacking systems increase productivity and labour efficiency.

Works with a variety of biodegradable films

Can be processed using PLA, PBAT, starch-based films, compostable films and other environmentally friendly materials.

How Biodegradable Bag Making Machine works?

1. Resin Preparation & Drying

Biodegradable raw material granules (e.g. PLA or starch-based blends) are very hygroscopic, meaning they absorb water from the atmosphere. The raw granules needed for extruding must go through a dehumidifying dryer. Excess moisture will lead to bubble formation, weak structure and tearing of the film during the process.

4. Feeding & Tension Management

The printed film roll is installed on the unwinding part of the Biodegradable Bag Making Machine. The feed rate is continuously controlled with high-precision servo motors and pneumatic tension controllers. Due to its high elasticity and tear resistance when it is subjected to sudden stresses, the sensitivity of tension control should be very high.

2. Film Blowing (Extrusion)

Dried bio-resins are fed into a special-purpose Film Blowing Machine. To avoid thermal degradation, the material is melted inside an extruder barrel while being controlled with very low melting temperature (typically 110°C to 140°C). It is then forced through a circular die, inflated with air to form a large vertical “bubble”, cooled by an air ring and rolled into a continuous dual layer film sheet on a take-up roller.

5. Sealing and Cutting

A heavy duty, temperature controlled sealing bar seals the film. Using localized heat and pressure, the bottom of the bag is seamlessly joined to the main body of the bag. After the seal, the film is cut by a high-speed mechanical knife to the desired bag length as programmed.

3. In-Line Printing (Optional)

If the bags need the brand logos, statutory warnings, and/or compostability certification stamps, the flattened film roll is passed through a flexographic printing press. It involves specially formulated eco-friendly, water-based inks that decompose in the environment.

6. Handle Punching & Stacking

Hydraulic and pneumatic punch-dies quickly punch out handles from a stack of sealed grocery bags for the T-shirt (W-cut/U-cut) version. This is adapted for D-cut or flat bags. Finally, an automated conveyor system counts, stacks and prepares the finished biodegradable carry bags for final packaging and shipment.
