The use of shrink film to wrap goods is mainly to meet multiple demands such as protection, packaging efficiency, display effect, safety and cost control. The following is the specific analysis of the reasons:
1. Protect the integrity of the goods
Fixation and anti-scattering: After the shrink film adheres to the product and shrinks, it can firmly bind multiple independent items (such as beverage bottles, cans, stationery combinations) together, preventing them from shifting or scattering during transportation.
Dust-proof and moisture-proof: It forms a sealed barrier to block dust, water vapor, oil stains, etc., and is especially suitable for goods with high cleanliness requirements such as food and electronic products.
Impact resistance and cushioning: Reduce damage from friction, collision or drops during transportation (such as glass bottles, toys).
2. Enhance packaging efficiency and reduce costs
Automated rapid packaging: Shrink film can be wrapped at high speed through a heat shrink machine, which is more than 10 times faster than traditional manual strapping, making it suitable for large-scale production (such as mineral water and express packages).
Save material costs: Compared with paper boxes or hard packaging, shrink film is lighter and thinner, reducing logistics freight and packaging costs.
Reduce fillers: No additional cushioning materials such as foam and cardboard are required.
3. Enhance the display effect of the products
Transparent display: Materials such as PVC and POF have high transparency, allowing consumers to directly see the appearance of the products (such as fruits and gifts), which promotes purchase decisions.
Brand promotion: It can print brand logos, product information or promotional content, transforming into "mobile advertising" (such as cosmetics, beverages).
4. Security and anti-counterfeiting requirements
Anti-tampering and anti-theft: The one-time shrinkage feature ensures that the packaging will not be damaged after being opened, reducing the risk of substitution or theft (such as for electronic products and high-priced goods).
Anti-counterfeiting verification: Some shrink films are combined with anti-counterfeiting labels or QR codes to help identify genuine products.
5. Adapt to special needs
Irregular shapes: It can perfectly wrap irregular-shaped goods (such as toys, tools, medical devices), which is difficult to achieve with paper boxes.
Preservation function: Food-grade shrink film can extend the shelf life (for example, shrink packaging of fresh meat can reduce oxidation).
Cold chain compatibility: PE material is low-temperature resistant and suitable for the transportation of frozen food.
6. Common application scenario examples
Food and beverages: Whole cases of mineral water bundling, canned food fixation, and fresh food preservation
Daily chemical products: Multi-piece set shampoo bottles, moisture-proof plastic-sealed tissues
Electronic products: Dust-proof packaging for batteries and data cables, anti-counterfeiting film on the outside of mobile phone boxes
Pharmaceuticals: Moisture-proofing of medicine bottles and aseptic protection of medical devices
Industrial products: Rust prevention for hardware tools, scratch prevention for building materials
Due to its high efficiency, economy and multi-functionality, shrink film has become the mainstream choice for commodity packaging, especially suitable for scenarios that require mass production, transportation protection or visual display. Enterprises will choose different materials of shrink films (such as PVC, POF or PE) based on product characteristics (such as weight, shape and shelf life requirements).
