Choosing the Right Size PVC Shrink Film

PVC shrink film is a versatile packaging material known for its ability to conform to the shape of products and provide a tight, protective seal. Selecting the correct size of PVC shrink film is crucial to ensure efficient packaging and a professional presentation. This guide outlines key factors to consider when determining the size of PVC shrink film needed for your specific packaging requirements.

1. Measurement of Product Dimensions

Start by measuring the dimensions of the product you intend to package. Take into account the length, width, and height of the item, as well as any protruding or irregular shapes. Ensure that the measurements are precise to determine the appropriate size of shrink film needed.

2. Calculate the Total Surface Area

Calculate the total surface area of the product, including all sides. This can be done by adding the surface area of each side and any additional areas that need coverage. The total surface area will guide you in selecting a PVC shrink film roll with adequate width and length to accommodate your product.

3. Consider the Shrink Ratio

Take into consideration the shrink ratio of the PVC shrink film. Shrink ratio refers to the percentage by which the film will shrink when heat is applied. Common shrink ratios include 60%, 75%, and 100%. Ensure that the chosen film accommodates the dimensions of your product after the shrinkage process.

4. Allowance for Sealing

Consider the allowance needed for sealing the ends of the PVC shrink film. Typically, an extra length is required for effective sealing, especially if using a heat sealer. Ensure that the film size accounts for this additional length to achieve a secure and professional-looking seal.

5. Compatibility with Shrink Equipment

Check the compatibility of the selected PVC shrink film size with your shrink packaging equipment. Different machines may have specific requirements regarding film width and core size. Ensure that the film roll fits seamlessly onto your equipment for smooth and efficient packaging.
