Skin pack

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

Skin pack, or skin packaging, is a type of carded packaging where a product (or products) is placed on a piece of paperboard, and a thin sheet of transparent plastic is placed over the product and paperboard.[1][2] [3] The printed paperboard usually has a heat-seal coating. The plastic film (LDPE, PVC, ionomer, etc.) is softened by heat and draped over the product on the card. Vacuum is sometimes used to assist a firm fit. The film bonds to the heat-seal coating on the paperboard. The skin-packed piece then may need to be cut into individual units.

Self-adhesive film with uncoated card is also sometimes used.[citation needed]

Skin packaging somewhat resembles a blister pack, with the major difference being that the plastic surrounding the product is formed over the product, instead of being pre-formed.

Types of plastic film:

  • Polyethylene
  • PVC
  • Ionomer
  • PET

Meat[edit]

Vacuum and skin packed meat

Fresh meat can be vacuum packed and skin packed. Specialized packaging operations are needed to maintain product appearance and safety. Temperature control during the cold chain is needed for proper shelf life.[4]
