PVC cling film once reigned supreme in the cling film market due to its high transparency, excellent stretchability, and low price.

The "toxic cling film" incident of a few years ago is still fresh in our minds. Some unscrupulous merchants, driven by profit greed, added DEHA, a plasticizer explicitly banned by the country, to PVC cling film. Once ingested, this plasticizer can disrupt the endocrine system and even increase the risk of certain diseases.

However, the "all-round manager" also has its "little pride." Due to the higher production cost of PVDC, its price is also significantly higher than PE and PVC cling film. If you're not a stickler for extreme preservation results or have a limited budget, PE cling film is more than enough to meet your daily needs.

PLA (Polylactic Acid) Cling Film: The Environmental Guardian, the "Darling" of the New Era

In recent years, with the rise of environmental awareness, PLA cling film has emerged as a rising star in the cling film world. It's like an environmental guardian, advocating for "green, safe, and biodegradable," quickly gaining a loyal fanbase.

Unlike traditional plastic cling film, PLA cling film's raw materials come from corn and other plant starch. After use, it can be completely degraded by microorganisms in nature, leaving no environmental pollution, truly embodying "taken from nature, returned to nature."

However, the price of environmental friendliness is often a higher cost. The production process of PLA cling film is more complex, and its price is relatively higher as well. If you're willing to contribute to environmental protection, PLA cling film is undoubtedly your ideal choice.

How to Choose and Use Cling Film: Keep Your Eyes Open, Build a "Safety Barrier"

After understanding the "character traits" of different cling film materials, you should have a clearer understanding of how to choose cling film.

When selecting cling film, we must first keep our eyes wide open and thoroughly examine the labels. Reputable cling film producers will clearly indicate the material, production date, expiry date, and usage precautions on the packaging. Choosing cling film from reputable manufacturers is like securing "safety insurance" for your food.

Besides looking at the labels, we can also touch the cling film to sense its "texture." PE cling film feels quite soft and easily stretches; PVC cling film feels harder and less flexible.

After selecting your preferred cling film, we must learn how to use it correctly to maximize its effectiveness and safeguard our health.

When using cling film, we should avoid direct contact with food, especially those with high oil content. This is because cling film may release harmful substances at high temperatures, contaminating food and jeopardizing our health.

Also, avoid placing cling film in a microwave or oven for heating. Cling film has limited heat resistance. If the temperature is too high, it may melt and deform, or even release harmful substances.

We should store cling film in a cool, dry place, out of direct sunlight. Cling film exposed to sunlight can easily age, affecting its lifespan.

"Film" preservation might seem simple, but it actually involves a lot of knowledge. I hope this article has given you a more comprehensive understanding of cling film, helped you learn how to choose and use it effectively, and allowed this small piece of cling film to become a guardian of our healthy lives!
