PVC shrink film is a popular packaging material used to wrap and protect various products, including food items, consumer goods, and industrial products. It is a type of thermoplastic polymer that becomes soft and pliable when heated and can be stretched and molded to fit the shape of the item being packaged. PVC shrink film is commonly used for its durability, clarity, and cost-effectiveness. Here is a buying guide for PVC shrink film to help you choose the right type for your needs.
The gauge thickness of PVC shrink film refers to its thickness and is measured in mils (thousandths of an inch). A higher gauge thickness indicates a thicker and more durable film. The thickness of PVC shrink film can range from 40 to 100 gauge, with 60 gauge being the most commonly used. The thicker the film, the stronger it is and the better it can protect the item being packaged. However, thicker films are also less flexible and more difficult to handle. For most applications, 60 gauge PVC shrink film is sufficient, but you should consider the type of product being packaged and the level of protection required before selecting the gauge thickness.
Width and Length
The width and length of PVC shrink film refer to the dimensions of the film roll. The width of PVC shrink film can range from 4 to 60 inches, while the length can range from 500 to 10,000 feet. The width of the film should be selected based on the size of the item being packaged, while the length should be selected based on the amount of film required for each packaging operation. For small items, a narrower film roll may be suitable, while larger items require wider films. The length of the roll will depend on the frequency of packaging and the amount of film required per packaging operation.
The shrink percentage of PVC shrink film refers to the amount of shrinkage that occurs when the film is heated. PVC shrink film typically has a shrink percentage of 40% to 70%, with 60% being the most commonly used. The shrink percentage is an important factor to consider because it affects the fit and appearance of the package. A higher shrink percentage can result in a tighter and more uniform fit, while a lower shrink percentage may result in loose or uneven packaging. It is important to consider the type of product being packaged and the desired appearance of the package when selecting the shrink percentage.
The clarity of PVC shrink film refers to its transparency and is an important factor to consider for products that require a clear and visible packaging. PVC shrink film is known for its excellent clarity, which allows the product to be easily seen by the consumer. However, the clarity can be affected by the thickness and quality of the film. Thicker films tend to be less clear than thinner films, while lower quality films may have a cloudy appearance. When selecting PVC shrink film, it is important to consider the desired level of clarity based on the product being packaged and the overall presentation of the package.
Strength and Durability
The strength and durability of PVC shrink film are important factors to consider for products that require a high level of protection during shipping and handling. PVC shrink film is known for its strength and durability, which helps to prevent damage to the product during transit. However, the strength and durability can be affected by the gauge thickness and quality of the film. Thicker films tend to be stronger than thinner films, while higher quality films are more durable than lower quality films. When selecting PVC shrink film, it is important to consider the level of protection required based on the product being packaged and the shipping and handling conditions.
