Packaging your cargo to make it waterproof, weatherproof, and tamperproof is very easywith the help of shrink wrap. Cargo shrink wrapping is an easy process as it requires two basic elements, the rightkind of shrink film and heat. So not only can you protect your cargo but also maintain the look, feel, and long life of your cargo.
Shrink wrapor shrink film is a versatile polymer material used for the packaging of cargo. The process involves applying heat to the film either through a conveyor heat tunnel or an electric or gas heat gun enabling it to shrink tightly around the cargo placed within.
Shrink wrapis quite versatile and available in a variety of types, thicknesses, clarities,strengths, and shrink ratios. They can be either used as stand-alone or in combination with other shrink films or other packing material to create the required type of layering and protection for your cargo.
While trying to select the correct type of shrink wrap for your packaging needs, few questionsthat need to be kept in mind before your final selection are:
Is the Applied Shrink Force Safe for Your Product?
Shrinkforce can be defined as the clamping force that is exerted on the product beingshrink wrapped. It is measured commonly in pounds per square inch (PSI), a unit of pressure. Understanding the shrink force is essential to adjust the settings of your shrink machinery as cargo needs to be tightly contained without damaging the products within.
What Type of Shrink Orientation Would be Best for Your Product?
A shrink film can be made to shrink in one direction (preferentiallyoriented or mono-directional) or in both directions (bi-axially oriented or bidirectional).Preferentially oriented film shrinks differently in either direction. Using a preferentially oriented film ensures the usage of less film and prevents product distortion. Bi-axially oriented films shrink equally in both directions.
What are the Shrink Percentages Concerning Your Product?
Shrink wrap is classified by the amount of contraction or shrinkpercentage when heated. By using theshrinkage percentage, one can determine the size of the material required. Freeshrink is the amount of shrink-ability in a film before it makes contact with your product. High levels of free shrink allow you to get a better-looking package on difficult shapes and sizes.
How Resistant It is to Wear and Tear?
Every packaging material undergoes rough handling and improper storageconditions during transit. The resistance capacity defines the threshold valuesin which the shrink wrap will break and how hard it is to tear the wrap once it has been broken. Wraps with high resistance to breaking have lower resistance to tear and vice versa.
What is the Moisture Vapour Resistance Capability?
The moisture vapour transmission rate (MVTR) is a measure of how muchmoisture will or will not travel through the shrink wrap. For the increasedshelf life of your cargo, opting for low moisture transmission shrink wrap is important.
By determining the correct type of cargo shrink wrap you can ensure that your cargo is provided with the maximumprotection during transit and storage.
