Introduction

The packing film process is a crucial step in ensuring the protection and preservation of products. This article outlines the comprehensive process involved, from film selection to quality control measures. By understanding these stages, industries can enhance product safety and extend shelf life.

Film Selection

Selecting the appropriate film is the foundational step. Parameters to consider include:

• Thickness: Ranges generally from 12 to 100 microns, depending on product needs.
• Material: Common materials include polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC).
• Transparency and Opacity: Determines the visual branding and advertising capability.

Processing Techniques

Several techniques are employed in processing film for packing:

1. Extrusion: Involves melting plastic pellets and forming them into a film. High precision machinery controls thickness uniformity within ±5 microns.
2. Blown Film Extrusion: Creates a tubular film with a standard deviation of thickness below 3%.
3. Cast Film Extrusion: Produces sheets with consistent gauge control better than 2% variation.

Packing Methods

Various packing methods are tailored to product needs:

• Shrink Wrapping: Applies film that shrinks tightly over the product. Shrinkage rate is generally 40-50% for effective coverage.
• Stretch Wrapping: Uses stretchable plastic film to wrap around products. It offers 25-30% elongation depending on film quality.

Quality Control

Quality control ensures the packing film consistently meets industry standards:

• Strength Testing: Includes tensile and tear resistance tests, ensuring films withstand at least 20 MPa tensile strength.
• Barrier Properties: Tests the film's permeability to moisture and gases, aiming for less than 2 g/m²/day water vapor transmission.
