Yuhong manufactures Degradable Stretch Film using PE resin combined with degradable masterbatch technology. The film is used for pallet wrapping, warehouse packaging, transportation protection, and industrial packaging applications.
The material formulation modifies conventional PE stretch film characteristics while maintaining the wrapping functions required for packaging operations, including stretchability, film cling, load retention, and product protection.
Available production options include customized film thickness, width, roll length, core size, film type, and packaging format. The film is available in both hand stretch film and machine stretch film formats according to different wrapping processes.
| Feature | Degradable Stretch Film | Conventional PE Stretch Film |
|---|---|---|
| Polymer Stability | Controlled degradation when exposed to disposal conditions | High molecular stability (Non-degradable) |
| Mechanical Strength | High load containment & puncture resistance | Standard load containment & stretch force |
| Application Compatibility | 100% compatible with existing wrapping machines | 100% compatible with existing wrapping machines |
| Environmental Alignment | Supports corporate sustainability & ESG targets | Faces increasing global single-use plastic restrictions |
PE resin and degradable masterbatch are prepared according to the required formulation. Incoming materials are inspected before production to verify material specifications, batch consistency, and processing suitability.
Prepared materials are processed through extrusion equipment to form continuous stretch film. Production parameters, including extrusion temperature, film thickness, cooling conditions, and film tension, are monitored during extrusion to maintain consistent film formation.
After extrusion, the film is converted into finished rolls according to specification requirements.
Available formats include:
The conversion process includes roll cutting, core installation, roll winding, and packaging preparation.
Finished rolls are inspected before shipment.
Inspection items include:

Yes, it has a shelf life; under normal storage conditions, it is recommended to use it within 12–18 months. However, it will not simply "degrade on its own"—degradation requires specific triggers (such as prolonged UV exposure, high heat and humidity, or soil contact). In a cool, dry warehouse, its physical properties remain very stable, showing little difference from standard film.
Yes. Darker colors (like black or dark green) absorb more UV light and heat; theoretically, they degrade slightly faster than light-colored or transparent films. If your packaged goods require long-term outdoor storage, we recommend choosing transparent or light-colored formulations. For indoor warehousing and handling, the impact of color is negligible.
It can be recycled, but it must be collected separately from standard PE film. In practice, if biodegradable film enters the conventional PE recycling stream, it may compromise the quality of the recycled material; therefore, separate recycling or processing via industrial composting facilities is recommended. If neither option is feasible, degradation serves as the final disposal method.
Yes. High temperatures (e.g., exceeding 50°C inside a shipping container in summer) may cause the film to soften slightly and stretch more easily, though load retention may decrease. Low temperatures (e.g., -20°C in cold storage) make the film brittle, requiring a reduction in the pre-stretch ratio. We recommend selecting a formulation suited to your specific operating environment; we offer solutions tailored for both high- and low-temperature scenarios.
There is no fundamental difference. The primary distinctions between hand-grade and machine-grade films lie in thickness and stretch formulations, while the triggers for degradation remain the same. However, machine-grade films are generally thicker (18–35 μm) and may take slightly longer to degrade than thinner hand-grade films (10–17 μm) due to the greater volume of material per unit.
Yes. Clean scrap generated during production can be recycled, pulverized, and reintroduced into the extrusion line, mixed with virgin material at a specific ratio. However, the proportion of recycled material is generally kept within 10% to 20%; exceeding this range can compromise the film's tensile properties and degradation uniformity.
