Industrial-Grade Differences in Material Physical Properties

Stretch Performance

PE Film: Features?300%~800% high stretch ratio?with excellent elastic recovery. Pre-stretch technology reduces material usage by?30%~50%, significantly lowering packaging costs.

PVC Film: Stretch ratio limited to?100%~200%?with poor elastic recovery. Requires thicker film for equivalent strength, increasing material costs.

Puncture Resistance & Temperature Tolerance

PE Film: LLDPE film material delivers?exceptional puncture resistance, suitable for heavy cargo transport. Temperature range:?-60°C to 80°C?(excellent cold chain compatibility).

PVC Film: Moderate impact resistance; prone to brittle fracture at low temperatures (fails below -10°C), softens above 50°C (for indoor storage only, may delaminate during high-heat summers).

Adhesion & Clarity

PE Film: Features an adjustable adhesive layer that leaves no residue (protects product surfaces) and offers high light transmittance.

?PVC Film: Has inherent high tackiness but may leave adhesive residue (especially on aluminum spray-coated surfaces). Its light transmittance is relatively average.

Key Differentiators in Environmental Safety

Environmental Compliance

PE Film:?100% recyclable/re-granulatable, compliant with RoHS/REACH international regulations. No export barriers.

PVC Film: Contains chlorine and plasticizers;?releases carcinogenic dioxins during incineration. Strictly regulated under EU CLP legislation

Hygiene & Safety

PE Film:Food-grade plastic, odorless and no risk of additive migration.

PVC Film: May release vinyl chloride monomer (VCM). Requires the use of special plasticizers to meet food-grade standards, posing long-term exposure risks.

Industry Risk Mitigation

PE Film: Aligns with global green supply chain requirements (e.g., Apple/Amazon packaging policies), reducing ESG risks.

PVC Film: Being phased out in EU/US markets (e.g., restricted under Walmart’s “Sustainable Packaging Playbook”).

Industrial Selection

PE Stretch Film?：

Boasting exceptional mechanical strength, broad temperature adaptability, and environmental safety, PE stretch film dominates industrial logistics (heavy-duty pallets, cold chain logistics) and export packaging. In recent years, its demand has surged in sectors such as e-commerce, household storage, produce packaging, horticultural grafting, and sealing/leak prevention.

?PVC Stretch Film?：

PVC stretch film is only recommended for short-term indoor display applications under light loads and must undergo compliance evaluations with environmental regulations.

Data Support:

?According to a 2024 Frost & Sullivan report, PE films hold over 80% of the global industrial packaging market share, while PVC’s market share continues to decline.
