How to Select the Right POF Shrink Film Based on Packaging Machine Characteristics

The coordinated application between Shrink Film and packaging machines is crucial for improving packaging quality and production efficiency. Only by precisely matching the shrink film according to the specific characteristics of different packaging machines can the full potential of the equipment be released, ensuring efficient and stable packaging operations.

1.Corner Cutting Machine

Fully automatic corner cutting packaging machines are widely used in high-end product packaging, such as toys, health products, gifts, and electronics. Its core function is to perform corner cutting during the packaging process, ensuring precise adaptation for both rectangular products and those with special structures like hooks. The finished packaging has no excess edges, with clean and precise cutting lines. This automated operation significantly reduces labor costs while ensuring consistent packaging quality, making it ideal for mass production.

Given the strict requirements for packaging quality and efficiency, the Pof Shrink Film used with corner cutting machine must possess excellent performance:

• High tear and puncture resistance – To withstand mechanical stress during cutting and prevent damage.
• Excellent flexibility – Ensures smooth passage through complex packaging paths without breakage from bending or twisting.
• Stable and uniform shrinkage rate– Guarantees smooth packaging appearance and enhances product aesthetics.
• Strong heat seal strength with an appropriate temperature range – Meets the fast and precise sealing demands of corner cutting machine.

In practical applications, it has improved packaging quality and product value, gaining widespread adoption among well-known domestic manufacturers.

2.Pillow Packaging Machine

Pillow packaging machines, as a representative type of fully automatic horizontal packaging equipment, are designed for flat, elongated, or bagged products, forming a "pillow-shaped" package (sealed at both ends with a bulging middle). They are widely used in food, pharmaceuticals, daily chemicals, and agricultural processing, particularly for items like biscuits, bread, candy, chips, tablets, and tissue products. It operate at extremely high speeds—typically 3 to 4 times faster than folding machine—while demanding stringent sealing quality for efficient continuous packaging of uniform products.

Due to their high-speed operation and strict sealing requirements, the POF Shrink Film must meet specific performance criteria:

• High heat seal strength – Ensures secure sealing at high speeds.
• Fast heat sealing speed – Matches the rapid operational rhythm of pillow packaging machines.
• Moderate tensile strength and elongation – Provides sufficient durability while maintaining flexibility to adapt to various packaging deformations.
