Plastic film blowing machines are mainly divided into the following types, each with different functions and application areas:
1. Ordinary single-layer film blowing machine
Function: Produce single-layer plastic film, commonly used in food packaging bags, supermarket shopping bags, agricultural mulch, etc.
Material: PE (LDPE, HDPE, LLDPE), PP, etc.
Features: Simple structure, low cost, suitable for ordinary packaging needs.
2. Multi-layer co-extrusion film blowing machine (double-layer, three-layer, five-layer, seven-layer, etc.)
Function: Produce multi-layer composite film to improve the strength, barrier properties, puncture resistance, etc. of the film.
Material: PE, PP, EVA, PA, EVOH, etc., different materials can be combined to enhance the function.
Features:
Can be used for food fresh-keeping packaging, high barrier packaging (such as vacuum packaging bags), medical packaging, etc.
Improve oil resistance, moisture resistance, and oxidation resistance.
Suitable for packaging materials with high functional requirements.
3. High and low pressure film blowing machine
Function: Can produce HDPE (high-density polyethylene) and LDPE (low-density polyethylene) films.
Features:
HDPE film: good toughness, low transparency, high stiffness, suitable for vest bags, garbage bags, etc.
LDPE film: high transparency, good softness, suitable for supermarket shopping bags, food packaging bags.
4. Water-cooled film blowing machine
Function: Use water cooling technology to quickly cool the film to improve transparency and smoothness.
Material: Mainly suitable for PP, PE, etc.
Features:
The produced film has high transparency, uniform thickness and bright surface.
Applicable to products with high transparency requirements such as food packaging, fruit and vegetable packaging.
5. Bubble film blowing machine
Function: Produce bubble film (cushioning packaging material) for express packaging, electronic product packaging, etc.
Material: LDPE.
Features:
Through bubbles to form a buffer protection to prevent product damage.
Can produce single-sided and double-sided bubble film to enhance protection capabilities.
6. Degradable material film blowing machine
Function: used to produce degradable plastic films, such as PLA, PBAT, PVA and other environmentally friendly materials.
Features:
Produce environmentally friendly plastic bags, such as degradable shopping bags, biodegradable garbage bags, etc.
Applicable to markets with strict environmental regulations, such as Europe and the United States.
7. Recycled material film blowing machine
Function: Use recycled plastic particles for film blowing, reduce costs, and promote resource recycling.
Material: Recycled PE, PP, etc.
Features:
Applicable to the production of industrial packaging bags, garbage bags, etc.
Reduce production costs and comply with environmental protection policies.
8. Agricultural film blowing machine
Function: Used to produce agricultural mulch, greenhouse film, etc.
Material: PE, EVA, etc.
Features:
Can produce wide-width films to improve the heat preservation and moisture retention effects of crops.
Anti-UV, anti-fog and other functions can be added.
Different types of film blowing machines are suitable for different industries and product selections, and suitable equipment can be selected according to needs.
