Non-Crosslinked Recyclable PEF Shrink Film Suppliers in China | Factory Direct High-Quality Polyolefin Film
Product Advantage
Advantage of High Transparency
Compare with POF and Cross-linked Shrink Film, the transparency of PEF is much more better, which are under the same optical conditions.
The packaging effect is excellent, it can be applied to high-end product packaging and suitable for automatic and semi-automatic packaging machinery.
Advantage of Low Shrinkage Temperature
Shrinkage temperature suggestion: 135-150℃
(need to be adjusted according to different packaging machine temperature and transmission speed)
Small and Soft Corners
Compare with the traditional POF shrink film, PEF has better shrinking outcome with soft corner and strong sealing. The softness of PEF is increased by about 40%. The PEF performance data is very lose to that of the cross-linked film. The corners after shrinking are small and soft.
Outstanding Shrinkage Performance
In the silicone oil test of 120℃-150℃ film surface temperature, the shrinkage rate of PEF is better than that of POF, which is close to that of cross-linked films. Upon the shrinkage effect, PEF has similar performance as that of cross-linked films.In the silicone oil test of 115°c film surface temperature,the shrinkage rate of PEF is the highest among the three types of films, reaching more than 50%. The shrinkage effect of PEF at low temperature is excellent.
Energy Saving Potential
PEF has excellent low-temperature shrinkage performance, which can offer potential cost saving opportunity for enterprise production.
Excellent Optical Performance
In terms of haze testing, the data of PEF shrink film just 2.8%. The result indicates that the PEF shrink film has excellent light transmittance, which is up to 45% higher than that of POF and cross-linked films.
Excellent Tensile Strength
The machine direction and transverse direction tensile strength of the PEF reaches more than 100 Mpa, with good tensile properties and flexibility.

Data Sheet
Frequently Asked Questions
How does the transparency of PEF compare to POF and Cross-linked films?
Under the same optical conditions, the transparency of PEF is significantly better than both POF and Cross-linked Shrink Film, providing an excellent packaging effect for high-end products.
What is the recommended shrinkage temperature for PEF shrink film?
The suggested shrinkage temperature is between 135-150℃. However, this temperature should be adjusted based on the specific packaging machinery temperature and transmission speed.
Why are the corners of PEF shrink film described as small and soft?
Compared to traditional POF, the softness of PEF is increased by approximately 40%, making its performance data closely resemble that of cross-linked film, resulting in smaller, softer corners after shrinking.
Does PEF shrink film offer energy-saving benefits?
Yes. PEF features outstanding low-temperature shrinkage performance (reaching over 50% shrinkage rate at a 115°C film surface temperature), which provides enterprise production with potential cost-saving opportunities.
What is the tensile strength and flexibility of PEF film?
PEF has excellent tensile properties and flexibility, with both machine direction (MD) and transverse direction (TD) tensile strength reaching more than 100 Mpa.
Is PEF shrink film recyclable?
Yes, PEF film is recyclable in communities that have active programs and facilities in place for the collection and recycling of plastic films.
