![]() When cooled properly, the film’s molecular characteristics are set, so it remains in this stretched state until sufficient heat energy is applied for the molecule chains to shrink back to their original form. More simply, the molecules reorient from their initial random pattern to ultimately fit the mold of their contents. When the film is warmed, the structureless regions of the chains are straightened and aligned to the direction of orientation. The molecules of a shrink film sheet or tube are randomly intertwined, meaning they are coiled and twisted with no particular alignment. So, how exactly does this happen? The science of shrink wrap can be explained in terms of molecular behavior. This process results in a clear, durable barrier of protection around the product. Heat is applied to the film – by either a conveyor heat tunnel or an electric or gas heat gun – which catalyzes the film to shrink tightly around the item placed within. Shrink wrap (also referred to as shrink film or shrink wrap) is a versatile polymer material used for the packaging of finished goods. This guide is a comprehensive source of information about shrink wrap for product packaging. ![]() To bring your products to the market with shrink film, this guide will give you all you need to know including what shrink film is, what it’s typically used for, what types are available, and how each benefits different products, how much shrink film costs, and whether it’s right for your business. ![]() Given the flexibility, durability, and other valuable advantages of using shrink film, many companies employ this option to package their products. You'll also be able to bring a layer of confidence to your consumer, and stand out with the protective shine of shrink wrap when applied appropriately! With just a roll of shrink film and a heating source, you have all the tools you need to waterproof, weatherproof and tamperproof just about anything, regardless of size. From the look to the feel to the longevity of your products, how well are your products comparing with similar products in the market? Shrinkwrapping is an easy process requiring two basic elements: the right kind of shrink film and heat. Bringing your product to your consumer needs to be an excellent experience.
