RQ-45 Fully Biodegradable Film Blowing Machine
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.

Monolayer Blown Film Machine
Simplicity, stability, and cost efficiency – Ideal for general packaging, garbage bags, T-shirt bags.
1. One-touch intelligent control, high output
User-friendly interface with smart temperature control reduces reliance on operator experience. Runs 24/7 with excellent film flatness.
2. Ultra energy-saving, half the electricity cost
Optimized screw L/D ratio and air ring design cut energy consumption by 20–30% vs. conventional machines. Long-term savings can pay for another machine.
3. Zero-entry maintenance
Modular design with widely available standard components. Quick part replacement by any general mechanic – minimal downtime.
4. Precise gauge uniformity, accurate grammage
High-precision micro-grammage controller keeps thickness variation very low, saving material cost and boosting printing/bag-making yield.
5. Fast payback workhorse
Low initial investment, stable output. Ideal for standard bags – typically recovers investment within 6–8 months.

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.
