Recyclable Non-Crosslinked PEF Shrink Film from China Suppliers & Factory - High Transparency & Strong Sealing
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
Q1: How does the transparency of PEF shrink film compare to POF?
Under the same optical conditions, the transparency of PEF shrink film is significantly better than both POF and traditional Cross-linked Shrink Film, making it ideal for high-end product packaging.
Q2: What is the recommended shrinkage temperature for PEF film?
The suggested shrinkage temperature is between 135-150℃. However, this should be adjusted based on your specific packaging machine's temperature settings and transmission speed.
Q3: What makes PEF shrink film energy efficient?
PEF has outstanding low-temperature shrinkage performance. For instance, in testing at 115°C film surface temperature, PEF reached a shrinkage rate of over 50%, which offers significant energy and cost-saving potential.
Q4: How soft are the corners of PEF shrink film after shrinking?
PEF shrink film provides small and soft corners with strong sealing. Its softness is increased by approximately 40% compared to traditional POF shrink film, performing very close to cross-linked films.
Q5: What is the tensile strength of PEF shrink film?
PEF shrink film exhibits excellent tensile properties and flexibility, with both machine direction (MD) and transverse direction (TD) tensile strength reaching more than 100 Mpa.
Q6: Is PEF shrink film environmentally friendly and recyclable?
Yes, PEF shrink film is recyclable in communities that have programs and facilities in place for collecting and recycling plastic films.
