Tyhjiöpakkauskalvot

Tyhjiöpakkauskalvot are specialized plastic films designed for vacuum packaging applications. These films are crucial for extending the shelf life of food products and other perishable items by removing air from the packaging before sealing. The primary function of tyhjiöpakkauskalvot is to create a barrier against oxygen, moisture, and other contaminants that can lead to spoilage and degradation.

The materials used in tyhjiöpakkauskalvot are typically multi-layered laminates, combining different types of plastics to achieve desired properties. Common components include polyethylene (PE) for sealing, polyamide (PA) for puncture resistance and barrier properties, and often ethylene vinyl alcohol (EVOH) for superior oxygen barrier. The specific composition of the film can be tailored to the product being packaged, considering factors like fat content, acidity, and potential for sharp edges.

These films are characterized by their excellent sealing capabilities, allowing for an airtight closure when used with vacuum sealing machines. They are also designed to be durable and resistant to tears and punctures, ensuring the integrity of the package throughout its lifecycle. The transparency of many tyhjiöpakkauskalvot allows consumers to see the product inside, which is an important marketing aspect for many food items.

Applications for tyhjiöpakkauskalvot are widespread, particularly in the food industry for meat, cheese, fish, and ready-to-eat meals. They are also used for non-food items where protection from environmental factors is necessary. The use of tyhjiöpakkauskalvot contributes to reduced food waste by significantly increasing the preservation period of packaged goods.
