Characteristics and Advantages of PE Stretch Film Packaging

Unitization is one of the prominent features of PE stretch film in packaging. Its strong wrapping force and retraction ability compactly bind products into a single unit, transforming scattered items into an integral whole. Even in unfavorable environments, the products remain secure without sharp edges or adhesive residues to prevent damage.

PE stretch film provides primary protection for packaging by forming a lightweight, protective layer around the product. This layer prevents dust, oil, moisture, water, theft, and evenly distributing force to avoid damage caused by uneven pressure—a benefit traditional methods like strapping or taping cannot achieve.

The film offers excellent compression and fixation properties. Its stretching and retraction forces tightly wrap products into compact units, preventing displacement during transit. Adjustable tension ensures complex products fit snugly while soft items are securely compressed. This is particularly beneficial in industries like tobacco and textiles.

Using PE stretch film reduces costs. Compared to other methods, it can cut packaging costs to about 15% of box packaging, 35% of shrink film, and 50% of carton packaging. It also lowers labor intensity, improves packaging efficiency, and enhances the overall presentation.

PE stretch film has self-adhesive properties, working as a single-sided (cast) or double-sided (blown) adhesive film that clings to itself without leaving residue on items. It eliminates the need for heat-shrink processes, conserving energy and reducing costs. High transparency aids product identification and minimizes delivery errors.

Paragraph 6:
In summary, PE stretch film delivers excellent performance with convenient packaging. It is non-toxic, environmentally friendly, moisture-proof, water-resistant, dust-proof, corrosion-resistant, and highly durable against punctures and tears. It also boasts strong memory retention, reliable self-adhesion, and high transparency, making it a practical and versatile packaging solution.
