Green Plastic Replacement Becomes Inevitable, Degradable Materials Lead the Industry Trend
With the global implementation of dual‑carbon policies, the comprehensive promotion of plastic restriction bans, and the in‑depth popularisation of environmental sustainability concepts, the drawbacks of traditional petroleum‑based plastics have become increasingly evident. Pollution control, environmental compliance, and industrial upgrading are now core development topics in the packaging, agricultural, and daily‑necessities industries.
Thanks to their core advantages—compostability, zero residue, and non‑polluting properties—fully biodegradable materials are completely replacing traditional plastics. They are becoming the mainstream development trend of the global new‑material industry and a critical breakthrough for all sectors to achieve green transformation and compliant production.
As market demand for degradable packaging bags, agricultural mulch films, eco‑friendly garbage bags, and food‑packaging films continues to surge, the industry urgently needs to upgrade production capacity. However, most manufacturers face a key problem: ordinary universal blown‑film machines have poor adaptability and cannot meet the process requirements of PLA, PBAT, starch‑based, and other degradable materials. This has become the biggest bottleneck restricting enterprises’ quality improvement, efficiency gains, and green‑market expansion.

Unique Production Pain Points of Degradable Materials Cannot Be Solved by Universal Equipment
Biodegradable materials differ greatly from traditional PE and PP plastics in physical and rheological properties. They feature a narrow processing‑temperature window, low melt strength, high shear sensitivity, and are prone to thermal decomposition. When produced using conventional blown‑film machines, degradable materials are susceptible to overheating degradation, unstable film bubbles, frequent film breakage, uneven film thickness, numerous surface crystal defects, and high rejection rates.
This not only causes raw‑material waste and high production costs, but also fails to produce high‑quality degradable films that meet market standards. Simply renovating old equipment and applying universal process parameters cannot accommodate the exclusive production needs of degradable materials. Only targeted, customised core components can ensure stable, efficient, and high‑quality mass production.
Chenqi Custom Core Components Tailor‑Made for Degradable Materials
With years of experience in R&D and manufacturing of blown‑film equipment, Chenqi accurately grasps the production characteristics and industry pain points of degradable materials, breaking the technical limitations of universal equipment. We independently develop custom screws and precision die heads for all types of biodegradable materials, and launch exclusive blown‑film machines that completely solve the production problems of degradable films from the core.
Custom Screw Exclusively for Degradable Materials
For different degradable formulations—such as PLA, PBAT, and starch blends—we exclusively optimise the screw length‑to‑diameter ratio, compression ratio, and groove structure with a low‑shear, gentle plasticisation design. This effectively prevents excessive shearing and overheating decomposition of degradable raw materials, enabling uniform melting and stable plasticisation. It thoroughly improves film defects such as crystal spots, bubbles, and thickness deviation, greatly increasing the yield of finished products and production stability, and supporting long‑term, continuous mass production.
High‑Precision Custom Spiral Die Head
The die‑head structure is customised according to the unique rheological properties of degradable materials, with optimised melt flow channels and discharge angles to achieve uniform melt distribution and stable pressure output. It perfectly solves industry‑wide problems such as insufficient melt strength, easy bubble sagging, and unstable film bubbles. It ensures uniform discharge, regular forming, and controllable thickness accuracy. The produced degradable film has good toughness and high flatness, fully meeting the quality requirements of the high‑end market.

Full Machine Optimisation & Adaptation Empower Enterprises to Seize the Green Track
Chenqi’s exclusive blown‑film machine for degradable materials is not only equipped with customised core components, but also integrates a zoned precision temperature‑control system, a high‑efficiency cooling air ring, and a constant‑tension winding system—fully adapting to the production process of degradable materials. The equipment can stably produce various biodegradable films. After disposal, the products can be completely decomposed into water, carbon dioxide, and organic matter in a natural composting environment, without microplastic residue or secondary pollution—fully aligned with global sustainable development strategies and green environmental policies.
In the era of plastic replacement, environmentally friendly production capacity is the core competitiveness. Chenqi provides one‑stop degradable film production solutions for enterprises, including material‑adaptation testing, core‑component customisation, equipment commissioning, and after‑sales technical support. We fully support enterprises’ industrial upgrading, help customers seize the dividends of the global green packaging market, and achieve low‑carbon sustainable development.
