In the modern packaging industry, shrink film has become an important choice for commodity packaging due to its excellent protection, display and environmental protection characteristics. With the advancement of materials science, the types of shrink films are constantly enriched, and different types of shrink films are suitable for different packaging needs. This article will introduce the main classifications of shrink films and their application fields in detail to help foreign trade practitioners better understand this product.
PVC shrink film
PVC (polyvinyl chloride) shrink film is one of the earliest widely used shrink films, with low cost and high shrinkage rate (usually up to 50%-70%). It is suitable for collective packaging of products such as beverage bottles, food packaging, stationery, and toys. PVC shrink film has high transparency and good printing effect, and can clearly show the appearance of the product. However, due to the improvement of environmental protection requirements, some markets have restricted the use of PVC, especially in Europe, where companies prefer to choose degradable materials.
PETG shrink film
PETG (polyethylene terephthalate copolymer) shrink film is an environmentally friendly material with high transparency and tear resistance. Its shrinkage rate is usually between 70%-80%, which is suitable for high-end product packaging such as cosmetics, electronic products and pharmaceutical products. PETG shrink film does not contain chlorine and meets environmental standards, so it is popular in the European and American markets. In addition, it has good printability and can achieve high-quality graphic display.
PE shrink film
PE (polyethylene) shrink film is known for its flexibility and low temperature resistance, and is suitable for the packaging of beverages, daily chemical products and industrial products. It has a low shrinkage rate (usually 30%-50%), but high tensile strength, which can adapt to products of different shapes. PE shrink film is often used for pallet packaging, especially for heavy goods that need to be stacked for transportation.
OPS shrink film
OPS (oriented polystyrene) shrink film is a new type of environmentally friendly material with a shrinkage rate of more than 75%, which is suitable for high-demand packaging scenarios. It has excellent transparency and can clearly display product details. It is often used in the packaging of food, beverages and daily necessities. The degradability of OPS shrink film makes it an ideal choice to replace PVC, in line with international environmental protection trends.
Conclusion
There are many types of shrink films, and different materials have their own advantages in performance, environmental protection and application areas. When choosing shrink films, foreign trade companies need to comprehensively consider product characteristics, market demand and environmental protection requirements. With the increasingly stringent global environmental regulations, the market demand for environmentally friendly shrink films will continue to grow, and companies should pay close attention to industry trends to seize market opportunities.
