I. What is POF Shrink Film? Analysis of Core Advantages

POF shrink film (Polyolefin Orientated Film) is an environmentally friendly heat shrink film made of high-quality polyolefin raw materials through a double-bubble biaxial stretching process. It is the preferred alternative to traditional PVC shrink film and PP shrink film in the current packaging industry, widely used in various packaging scenarios due to its excellent performance.

Compared with traditional polyethylene blown film shrink film and PVC shrink film, POF shrink film has obvious advantages:

01 — Transparency

High transparency clearly displays product appearance to enhance shelf appeal.

02 — Durability

Excellent tear and puncture resistance protects products from damage during transportation.

03 — Low-Temp Resistance

Outstanding low-temperature resistance (non-brittle at -50℃) suits quick-frozen food packaging.

04 — Eco & Safety

Non-toxic, environmentally friendly and recyclable, complying with FDA food contact safety standards and EU environmental certifications.

05 — Automation

Compatible with various automatic packaging production lines, greatly improving efficiency and reducing packaging costs.

II. 2 Core Classifications of POF Shrink Film

POF shrink film is mainly divided into ordinary POF shrink film and cross-linked POF shrink film, both core products of Zhejiang Zhongcheng, meeting customers' diverse customization needs for different industries.

Mainstream · Cost-EffectiveOrdinary POF Shrink Film

Made by a five-layer co-extrusion process, ordinary POF shrink film has polypropylene (PP) as the surface layer and linear low-density polyethylene (LLDPE) as the core layer. Soft, environmentally friendly and pollution-free, it is the mainstream product in the market with excellent cost performance, widely used in packaging food, beverages and daily necessities. It can be customized in thickness and width, compatible with various automatic packaging equipment.
