The stretch-film vacuum packaging machine is a kind of equipment used for packaging food, pharmaceuticals, cosmetics and other products. It places the products in the packaging film and then uses vacuum to tightly wrap the film around the products, thus achieving the sealing and preservation of the products. This packaging method can effectively extend the shelf life of the products.

The stretch-film vacuum packaging machine is applicable to many different types of packaging films. Manufacturers of stretch-film vacuum packaging machines will introduce several common materials among them below.

Polyethylene (PE) film: Polyethylene film is one of the common packaging films. It has good flexibility and ductility and can adapt to products of different shapes and sizes. This film is characterized by being moisture-proof, dust-proof and anti-oxidation, and can protect the freshness and quality of food and other products.

Polypropylene (PP) film: Polypropylene film is another common packaging film. It has a certain degree of transparency and flexibility and is suitable for packaging a variety of products. The polypropylene film is characterized by being moisture-proof and dust-proof and is suitable for protecting food and other products. 

Nylon (PA) film: Nylon film is a kind of packaging film with relatively high strength and durability. It has good moisture-proof performance and gas barrier properties, which can extend the shelf life of food and prevent oxidation. Nylon film is suitable for packaging products that are easily affected by oxidation, such as meat, dairy products, dried fruits and vegetables.

CPP film: CPP (cast polypropylene) film is a packaging film with relatively good abrasion resistance and flexibility. It can provide good mechanical properties and sealing performance during the packaging process and is suitable for packaging various products.

PVC film: PVC (polyvinyl chloride) film is a common packaging film. It has excellent softness and transparency and is easy to process and form. PVC film is suitable for packaging food, pharmaceuticals and various other products.

PVDC film: PVDC (polyvinylidene chloride) film is an efficient moisture-proof and anti-oxidation packaging film. It has good barrier properties against gases, water vapor and spices and is suitable for packaging products with relatively high requirements for moisture-proof.

The above are the common packaging films applicable to the stretch-film vacuum packaging machine. Different packaging films have different characteristics and application scopes. Choosing the appropriate packaging film can better meet the preservation and protection needs of products.
