Why POF Film Prevails as Traditional PVC Suffers Heavy Setbacks

PVC heat shrink film, which once monopolized the packaging market, is now rapidly fading out of the mainstream market. Amid tightening environmental regulations, the inherent flaws of conventional PVC film have been fully laid bare, while POF heat shrink film has surged to dominance. The industry-wide shift from old to new packaging materials is an irreversible trend.
When it comes to environmental friendliness and product safety, PVC suffers from fatal drawbacks. Containing chlorine and plasticizer additives, it is unsuitable for packaging food, maternal and infant goods, and daily chemical products. In contrast, Zhejiang Zhongcheng’s POF film is halogen-free, heavy-metal-free and non-toxic. It burns without producing polluting emissions and fully complies with domestic and foreign trade compliance standards, boasting top-tier safety performance.
There is a stark performance gap between the two materials in packaging appearance and practicality. PVC delivers poor light transmittance and uneven shrinkage, resulting in loose, wrinkled packaging. It is also brittle by nature and prone to cracking under low temperatures, leading to high breakage rates during transportation and greatly downgrading the premium feel of finished goods. Zhongcheng POF film features ultra-high clarity and uniform tight shrinkage that fits irregularly shaped products perfectly. It boasts outstanding flexibility, tear and puncture resistance, as well as anti-aging properties, elevating the high-end visual appeal of products on retail shelves.
POF film also holds distinct advantages in production efficiency and overall costs. It is compatible with all types of fully automatic packaging machinery for smooth, high-speed operation. In addition, POF film has a lower density, covering a larger surface area per kilogram. Though its unit price is slightly higher, it generates less material waste, cuts labor expenses and eliminates extra compliance rectification costs, bringing down total packaging expenses far below those of PVC.
With overwhelming advantages across cost performance, safety, visual presentation and production efficiency, the phasing-out of PVC film is inevitable. As a leading domestic packaging manufacturer, Zhejiang Zhongcheng foresaw the doomed fate of PVC film. It independently developed proprietary production processes for POF heat shrink film, establishing itself as an industry benchmark.
