The upgrade of environmental protection policies is driving the replacement of traditional plastics with biodegradable materials such as PLA and corn starch-based tubes, which are widely used in food service, medical, personal care, daily chemical, and toy industries. The PLA/PP biodegradable plastic straw production machine is specially designed for small-diameter, thin-wall tubing, enabling stable mass production of single-color and multi-color straws as well as various small tubes. With high automation and broad material compatibility, it is an essential production solution for eco-friendly tube processing enterprises.

PLA PP Biodegradable Plastic Drinking Straw Production Machine Overview

The PLA/PP biodegradable plastic straw production line is an automated extrusion system specifically engineered for small-diameter, thin-walled tubing, focusing on the manufacture of eco-friendly, biodegradable products. Supporting both single-color and multi-color co-extrusion, the equipment features a high degree of automation and stable operation. It meets the mass production needs for small-diameter tubing across industries such as food service, medical supplies, and toys, making it a premier choice for eco-friendly tubing processing.

Core Equipment Structure

The production line features a compact, integrated design that enables fully automated, continuous manufacturing. Equipped with a comprehensive set of core components, it ensures high precision and stability in the finished products.

1. Main Extruder and Forming Die

Utilizes a specialized extruder with precise temperature control tailored for PLA and modified biodegradable materials, ensuring uniform plasticization. Paired with a precision die designed for small-diameter tubing, it delivers a steady, even output, effectively resolving common issues associated with biodegradable materials—such as deformation and uneven wall thickness during extrusion.

2. Cooling and Sizing System

Equipped with a circulating constant-temperature sizing water tank, the system rapidly cools and sets the tubing through water circulation. This quick solidification prevents bending, shrinkage, and deformation, ensuring excellent roundness and dimensional accuracy.

3. Haul-off and Fixed-Length Cutting Unit

A high-precision haul-off mechanism feeds material at a constant, finely adjustable speed that perfectly synchronizes with the extrusion rate. The automatic cutting system performs precise, fixed-length cuts, resulting in clean edges without burrs and highly uniform finished products suitable for standardized mass production.

Multi-Color Co-Extrusion Configurations

This series offers a wide range of models with customizable co-extrusion configurations to meet diverse production requirements. Options include basic single-color models, dual-color layered or striped models, and custom multi-color co-extrusion models. Capable of producing solid-color, striped, and layered multi-color straws, the equipment supports a wide variety of styles and adapts well to market demands.

Applicable Materials and Products

The equipment offers strong compatibility and is specifically designed for eco-friendly materials and thin-walled, small-diameter tubing. Compatible raw materials include PLA (biodegradable), corn starch-based modified materials, and PP (polypropylene) plastics. This versatile machine is capable of producing a wide range of products—including biodegradable straws, PP plastic straws, lollipop sticks, cotton swab sticks, fine medical tubing, and various hollow toy tubes—thereby significantly reducing equipment investment costs for customers.
