Bi-axial High-Contraction PETG Shrink Film for Spherical Packaging and Full-Capsule Sealing

Product Overview

Technical Specifications

Our Core Advantages

The primary technical advantage of this high-contraction bi-axial film is its ability to eliminate the "skirt effect" on rounded containers. By utilizing a high MD (Machine Direction) shrinkage, the material exerts vertical pressure that locks the label securely over the shoulders and base of spheres, providing a seamless 360-degree finish. Produced in a dust-free, controlled environment, the film features exceptional tensile strength and puncture resistance, making it ideal for heavy-duty promotional bundles.

The high-purity resin also ensures a smooth shrinkage curve, preventing the film from snapping or becoming brittle during high-speed thermal processing.

Applications

This functional PETG material is specifically designed for spherical consumer goods, such as round cosmetic jars, artisanal beverage bulbs, and sports-themed novelty containers. Its "full-capsule" sealing capability makes it the premier choice for promotional bundling, where two or more items must be held together by a tight, industrial-strength outer wrap.

Additionally, it is highly effective for high-end electronics packaging and luxury gift sets that require a premium, skin-tight protective layer. Converters rely on this versatile substrate to provide maximum shelf appeal while maintaining a durable barrier against scuffing and moisture during global logistics.

FAQ

Q1:Why is high MD shrinkage necessary for spherical packaging?

A: For spheres or curved objects, the film needs to shrink not just around the "waist" but also over the "poles." A high MD (Machine Direction) shrinkage provides the vertical pull needed to ensure the label conforms tightly to the top and bottom of the sphere, creating a smooth, capsule-like seal that single-direction films cannot achieve.

Q2:What is the typical shelf life?

A: Despite its high contraction rates, the film is engineered with optimized mechanical stiffness and consistent gauge control. This ensures it remains stable on the mandrel and does not jam in the cutting or application units, allowing for high-efficiency production even with complex bi-axial shrinkage requirements.

Q3:Can we request a specific thickness for our project?

A: No, because the film is formulated with high-tenacity virgin resin that maintains excellent elongation and tear resistance even at maximum shrinkage levels. This ensures that while it grips the product with significant force, it remains flexible enough to resist punctures and impact during handling and transport.
