With the arrival of the New Year, the demand for food storage and packaging is gradually increasing. As an indispensable packaging material in daily life, cling film has attracted more and more attention. Here, we will introduce to you the working principle, common types and materials of cling film, and focus on analyzing the advantages of PVC material as cling film.
Working Principle
Cling Film helps extend the shelf life of food through its unique material properties. Its working principle mainly relies on the adhesion and breathability of the membrane.
-Adhesion: Cling film has a moderate adhesive strength, allowing it to tightly seal food surfaces, preventing air and bacteria from entering. This effectively slows down oxidation, helping to preserve food freshness.
-Breathability: Modern cling film is designed with controlled breathability, enabling proper airflow to maintain optimal humidity and temperature, thus preventing spoilage caused by excessive dryness or moisture.
Waterproof and Insulating: Most cling films provide a protective barrier against external moisture, safeguarding food from contamination while preserving its internal moisture to maintain freshness
Common types and materials of cling film
There are many different types and materials of plastic wrap suitable for different uses. Depending on the material, plastic wrap can be divided into the following main types:
-PVC cling film (polyvinyl chloride)
-PE cling film (polyethylene):
-PO cling film (polyolefin)
-PLA cling film (polylactic acid)
Advantages of PVC material as cling film
a) Superior Adhesion and Wrapping Performance
b) Excellent Transparency and Gloss
c) High Stretchability and Flexibility
d) Excellent Moisture Resistance and Insulation
e) Cost-Effective and Accessible
As the demand for food packaging grows, cling film has become an essential, cost-effective solution in both homes and businesses. Recently, the production and export of plastic wrap from Shenzhen World Packing Industrial Limited have increased. PVC cling film remains a top choice due to its excellent transparency, adhesion, and cost-efficiency. While its environmental impact is a consideration, its advantages in everyday food packaging are undeniable. Selecting the appropriate material based on specific needs and applications can better preserve food freshness and taste.
