Cold Stretched Sleeve Film | Intelligent Packaging Solution Without Heating
Cold stretched sleeve film, also known as cold shrink film, achieves tight packaging through elastic retraction without heating, simplifying processes and reducing energy consumption. It is the ideal choice for modern efficient packaging.
Core Advantages
- Heat-Free Shrinkage:Triggers elastic retraction via mechanical stretching, avoiding damage to heat-sensitive products and suitable for diverse scenarios.
- High Elasticity & Strong Protection:Elastic recovery rate ≥90%, tensile strength ≥20MPa (longitudinal) and ≥15MPa (transverse), tightly wrapping to prevent abrasion and loosening.
- Energy-Saving & Efficient:No heating required, energy consumption reduced by 50%+ compared to heat shrink films. Supports manual/automated packaging for different production needs.
- Eco-Friendly Options:Offers conventional materials (PVC, polyolefin PE/PP) and eco-friendly films (degradable PBAT/PLA, recycled rPE/rPP).

Characteristic
Greentec 7/9-layer co-extrusion high-barrier filmline adopts specially designed screw barrel and mold, which
can process resin materials such as PA and EVOH, so that film products have excel-lent gas barrier perfor-
mance, it can effectively block the penetration of oxygen, nitrogen, carbon dioxide and water vapor, and
meet the various needs of different users for preservation, air tightness, corrosion and mois- ture resistance.
The machine is also equipped with automatic air ring, online thickness measuring system, weight-less feeding
system, these auxiliary configurations can effectively improve the film production and thickness uniformity.
Using linear variable temperature control technol-
ogy, the temperature control precision of the
cooling air inside the membrane bubble is
improved, so as to effectively control the shrink-
age of the film.
With more intuitive visual operation.
More optimized closed-loop control of the entire line.
Product application
The equipment can be used to produce cold and fresh barrier packaging, cooked food barrier packaging,
medical barrier packaging, etc.
