Optimization plan for existing production lines of biodegradable materials
The thickness of the bag can be equipped with feeding weight control and automatic control of the pulling speed. The traditional process involves manual control of "pulling speed - thinning of the film, pulling speed - thickening of the film"
Automatic roll changing, no need for manual cutting, (With the improvement of intelligence, labor costs have been greatly reduced, with one person watching five or more machines)
Replacing a single screw machine with a dual head (like one engine supplying two cars) saves energy and costs.
Single layer ABA co extrusion, material composite (saving about 30% of raw material costs, adding recycled and modified materials to the middle layer. The inner and outer layers remain unchanged. The bag can be made thicker, with better texture and feel, increasing the core competitiveness of the product)
If biodegradable materials are used, the screw structure needs to be optimized to prevent the material from decomposing inside the screw, causing gas leakage in the blown film bubbles and unstable extrusion pressure.
