Low Tension PETG Shrink Sleeve 40micron Shrink Film For Bottles
Low Tension PETG Shrink Sleeve 40micron Shrink Film For Bottles
Product Overview
Our Low Tension PETG Shrink Film is a specialized substrate engineered for the delicate requirements of thin-walled and lightweight containers. Unlike standard films that may exert excessive pressure during heating, this "Soft-Shrink" material delivers high transverse shrinkage with significantly reduced contraction force. It is the ideal base film for converters providing labels for eco-friendly, lightweight plastic bottles and thin aluminum cans that are prone to thermal deformation.

Our Core Advantages
Anti-Deformation: Exerts minimal shrink force, ensuring that thin-walled or empty containers maintain their original structural shape without buckling.
High TD Shrinkage: Despite the low tension, it achieves an extraordinary shrinkage rate (up to 78%), allowing it to hug complex and high-contour bottle geometries perfectly.
Superior Flatness: Optimized for high-speed printing and seaming, ensuring smooth web handling and precise graphic registration.
Applications
Lightweight Beverage Packaging: Engineered for printing labels for ultra-light mineral water, soft drinks, and energy drink bottles.
Empty Bottle Sleeving: The perfect choice for production lines where sleeves are applied and shrunk onto empty, unpressurized containers.
Thin-Walled Dairy Jars: Provides a professional, "second-skin" fit for sensitive probiotic and yogurt containers without crushing the bottle walls.
Aerosol & Aluminum Cans: Ideal for high-definition branding on lightweight metal cans that require a gentle yet tight shrink finish.
FAQ
Q1:How does "Low Tension" differ from "Standard" PETG film?
A: Low tension film is formulated to reduce the mechanical stress applied to the bottle during the shrink process. It shrinks just as much as standard film but with a "softer" grip, preventing thin plastic from collapsing.
Q2: Does this film work with standard seaming solvents?
A: Yes. It is fully compatible with standard bonding agents (like THF), ensuring the seam remains strong and secure even when the film contours to irregular shapes.
Q3:What is the typical shelf life?
A: In a cool, dry warehouse (below 30°C), the film stays factory-fresh for 6 to 12 months. We recommend using it within this window for the best shrink performance.
