A Biodegradable Bag Making Machine is a specialized machine designed to produce environmentally friendly bags that decompose naturally over time through the action of microorganisms. These bags are made from biodegradable materials such as corn starch, PLA (Polylactic Acid), PBAT, PCL, or other plant-based or oxo-biodegradable compounds.

These machines are essential in the shift toward sustainable packaging, especially as many countries ban or regulate single-use plastics.

The machine takes biodegradable film rolls and processes them into finished bags through controlled heating, sealing, and cutting. It’s similar in structure to plastic bag machines but optimized for heat-sensitive and sometimes fragile biodegradable films.

A Two Layer Blown Film Plant is a type of plastic extrusion machine used to manufacture multilayer plastic films, primarily for packaging applications. This system uses the blown film extrusion process, but with two extruders and a specialized die that allows for the production of two distinct layers in a single film. Here's a detailed description:

A Two Layer Blown Film Plant produces co-extruded films by combining two different types of polymer materials, which can be tailored to provide various functional properties like barrier resistance, strength, flexibility, and clarity.

1. Twin Extruders:

   • Two separate extruders (usually labeled as A and B) melt and push out different resins.

   • Each extruder has its own barrel, screw, and temperature control zones.

   • Allows for different materials or additives in each layer.

2. Co-Extrusion Die Head (Two-Layer Die):

   • The melted polymers from both extruders are fed into a specialized die.

   • The die merges the two polymer streams into a single multilayer tube (film).

   • Die designs: spiral mandrel or stack-type.

3. Air Ring and Cooling System:

   • Surrounds the extruded bubble and provides cooling air to solidify the film.

   • Dual-lip or single-lip air rings are used depending on film thickness and clarity requirements.

4. Bubble Formation & Tower:

   • The extruded tube is inflated into a bubble with compressed air.

   • Height of the tower helps in cooling and stabilizing the bubble.

5. Nip Rollers & Haul-Off Unit:

   • Flattens and pulls the bubble upward to form a two-layer sheet.

   • Tension and speed control are crucial here.

A Biodegradable Cornstarch Bag Making Machine is a specialized bag conversion system designed to cut, seal, and finish biodegradable films made from cornstarch-based materials into various types of bags. It is specifically engineered to handle heat-sensitive, stretchable bio-films that behave differently than traditional PE/PP films.

These machines can produce:

• T-shirt bags

• Garbage bags

• Flat/side-seal bags

• Roll-on core or coreless bags

ABA Three-Layer Blown Film Plant, a highly efficient and cost-effective film extrusion system widely used in the flexible packaging industry. This type of plant is designed to produce strong, high-quality films while optimizing material usage, especially by incorporating recycled or lower-cost materials in the core layer.

An ABA film line is a co-extrusion system that produces a three-layer film structure (A-B-A) using just two extruders:

• Extruder A: Feeds both outer layers (A-A)

• Extruder B: Feeds the inner layer (B)

This clever configuration helps manufacturers save costs while still producing films with excellent surface quality, strength, and printability.

• Extruder A: For outer layers (usually virgin LDPE/LLDPE/HDPE)

• Extruder B: For the middle layer (recycled material, calcium-filled PE, or lower-grade polymer)

• Specialized die head for 3-layer distribution.

• Ensures balanced layer ratios and good adhesion between layers.

• Cools the extruded film bubble.

• Optional IBC (Internal Bubble Cooling) for better thickness control and higher output.

PPTQ stands for Polypropylene Tubular Quench, a specific process used to make high-clarity, high-strength biaxially oriented polypropylene (BOPP)-like films using the blown film process, but with some important differences.

It is specially designed for polypropylene (PP), which behaves differently from polyethylene and requires quenching (rapid cooling) to achieve optimal properties.

1. Material:

   • Primarily Polypropylene (PP)

   • Can include metallocene PP, random copolymer PP, or blends

2. Film Characteristics:

   • High gloss

   • Excellent clarity

   • High tensile strength

   • Good barrier properties

   • Stiffness and crisp feel – often used for packaging snacks, textiles, etc.

A 35mm blown film plant refers to the screw diameter of the extruder – relatively small, designed for low-to-medium output, ideal for narrow-width HM-HDPE film used in things like carry bags, liners, and packaging film.

HM (High Molecular) HDPE is a type of high-density polyethylene with:

• High tensile strength

• Good stiffness

• Excellent dimensional stability

• Slightly hazy (not as clear as LDPE or LLDPE)

It’s perfect for thin but strong films – like shopping bags or garbage liners.

A ABA Multilayer Blown Film Plant is an advanced plastic film extrusion system used to produce co-extruded multilayer films—commonly used for packaging applications such as carry bags, garbage bags, shrink wraps, and more. The "ABA" structure refers to a three-layer film configuration where the outer layers (A) are made of high-quality material, and the inner layer (B) is typically made from recycled or lower-grade material.

This configuration significantly reduces production cost while maintaining film strength and quality.

A blown film plant uses a process where molten polymer is extruded through a circular die and inflated into a bubble, then cooled, flattened, and wound into rolls.

In an ABA line, two extruders are used to create three layers:

• A Layer (Outer): Virgin or high-quality polymer

• B Layer (Core): Recycled or filler-enhanced material

• A Layer (Outer): Same as the first A layer

This setup helps optimize material usage, improve strength, and lower production cost.

A Non-Woven Carry Bag Punching Machine is a specialized machine used to create handle holes (die-cut or "U-cut") in non-woven fabric bags, which are widely used as eco-friendly shopping and packaging bags. These machines automate the punching process after the bag has been formed, increasing production speed, accuracy, and consistency.

It’s a vital part of a non-woven bag production line, especially when producing D-cut or U-cut carry bags.

The machine punches handle holes (typically D-cut) into pre-made non-woven bags using a hydraulic or pneumatic pressing system and a custom die. It works fast, cleanly, and with uniform hole shapes.
