Shrink packaging indicates the process in which sheets of transparent plastic film are wrapped around a product to form a solid, weather-resistant packaging layer.

Shrink packaging customarily refers to plastic films which have been pre-heated, stretched and cooled prior to use. This causes their initially randomly scattered molecules to align themselves in rigid structures, creating flat sheets of plastic film.

Shrink-wrap

When the shrink packaging films are applied to the product and re-heated, the molecules revert to their previous non-aligned state. This causes the plastic film to shrink and wrap itself tightly around the form and shape of the product (therefore the name ‘shrink-wrap’).

Benefits of shrink-packaging

Shrink packaging offers a versatile, cost-effective packaging solution for several reasons.

1- The materials used (plastic derivatives) are strong yet flexible, and provide effective protection, as well as making the product tamper-proof.

2- Shrink packaging is transparent, making it suitable for retail and wholesale display, and ideal for general marketing purposes due to its clear surface.

3- Shrink packaging is a relatively inexpensive option and ideal for low-cost packaging solutions.
