Three To Five Layer Co-Extrusion Upper Rotary Film Blowing Machine Set
Features and Uses:
lts extruder, cylinder and screw rods are made of quality alloy steel that have been nitrized and processed in a precision way. Hence it is sound in hardness,durable in corrosion resistance.
The specially-designed screw is of sound quality in plasticizing, which helps increase the production capacity, it is applied to blowing the plastic films like low density polyethylene(LDPE) and high density polyethylene (HDPE) and linear low density polyethylene(LLDPE) and all degradable plastic film. lt is widely applied to producing the packing bags for foodstuff, clothing, rubbish bag and vest ones.

ABC Blown Film Machine
High-performance customization – For heavy-duty sacks, liquid packaging, high-barrier food/chemical films.
1. Multi-component synergy, layered functionality
Layer C for anti-slip, layer B for toughness, layer A for low-temperature heat seal. One machine produces film combining puncture resistance and low-temp performance – ideal for high-value packaging.
2. Asymmetric structure design
Breaks symmetry limits – allows different materials inside vs. outside (e.g., metallocene inside for hot-tack, LLDPE outside for tear resistance). Delivers special physical properties.
3. Eliminates delamination & wrinkling
Precision distributor ensures perfect melt bonding inside the die. Prevents bubble instability, layer separation, and wrinkles caused by mismatched melt flow or temperature.
4. Low-temperature heat seal, high-speed packaging
Seal layer (layer C) can use low-initiation-temperature resin. Lowers sealing temperature – compatible with high-speed automatic packagers, ideal for heat‑sensitive products (chocolate, pastries).
5. Differentiation for high-margin orders
Easily co-extrude barrier layers (EVOH/PVB), anti-static, slip, anti-microbial, etc. Helps customers win high-profit orders in food and medical packaging.

Q1: What is a blown film machine used for?
Q2: Why does my blown film have uneven thickness?
Q3: How to fix frequent film bubble breaks?
Q4: What is the effect of blow‑up ratio (BUR)?
A: It is used to produce plastic film (e.g., LDPE, HDPE, LLDPE) by extruding molten plastic through a circular die and inflating it into a bubble. The film is then flattened and wound into rolls for further processing like bag making or lamination.
