Shrink Packaging - Shenzhen Lehua Packaging Materials Co., Ltd

Shrink packaging is a versatile packaging technique that encompasses shrink sleeve labels, shrink cap seals, and shrink wrap bags. In this packaging method, products are first wrapped with shrink film, which can be made from materials like PVC, PET, OPS or POF. The film is then heated to tightly conform and adhere to the product's surface.

Material	Shrinkage TD/MD	Thickness	Suit For	Advantage
PVC①	50% / 1-3%	30-50 micron	Shrink sleeves and shrink cap seal	The most common raw material at favorable price
PET	＞72% / 1-3%	30-50 micron	Shrink sleeves and shrink cap seal	High shrinkage makes it suit for any bottles
OPS	＞70% / 1-5%	40 micron	Shrink sleeves	Slow shrinkage allows for better fixation of the shrink film onto the bottle's surface
PVC②	50% / 15-40%	15-40 micron	Shrink bags and shrink tube	The performance of tear resistance is better
POF	55% / 55%	15-30 micron	Shrink bags	Flexible material with high transparency

☞Shrink Sleeve Label

Unlike traditional labels that are adhered directly to the product or container, shrink sleeve labels are applied loosely around the product or container and then subjected to heat, causing the label to shrink and conform tightly to the shape of the item. Shrink sleeve labels are commonly used in the packaging of beverages (bottles and cans), food products, personal care items, pharmaceuticals, and other consumer goods. They have become popular due to their ability to enhance shelf appeal, differentiate products, and communicate important information effectively.

☞Shrink Cap Seals

Also known as shrink neck bands or shrink tamper-evident bands, are a type of packaging material used to seal the caps or closures of bottles, jars, or containers. They are commonly used in the food, beverage, pharmaceutical, and cosmetic industries to provide a tamper-evident and secure seal to the product's container. They are a popular packaging solution due to their ability to ensure product integrity, enhance product presentation, and provide a sense of security to consumers.

☞Shrink Wrap Bags

Shrink bags are commonly used for packaging various products, including food items, stationery, toys, and other consumer goods. They are widely used in retail, e-commerce, and industrial applications, providing a protective barrier against dust, dirt, and moisture, keeping the enclosed items clean and well-preserved.
