One of the best packaging solutions that you can go for is shrink wrap for packaging. Shrinkwrapping is a very easy process that requires two things: heat (or steam) and the right type of plastic film. The plastic film is usually wrapped around the intended product/object. Then, heat and steam are applied onto this surface, causing the plastic to shrink and conform to fit the shape of the product/object.
