wrapperpackaging

Wrapper packaging, sometimes written as wrapperpackaging in some sources, is a packaging approach in which an outer wrapper, often a thin film, foil, or paper sheet, encloses a product to protect, conceal, and present it. The wrapper is typically formed around the item by a dedicated wrapping machine and can take several forms, including flow wrap (continuous film wrapped around the product and sealed at the ends), shrink wrap (film that is heated to snugly fit the item), and stretch wrap (film wrapped around pallets or bundles for stability). Common materials include plastic films such as oriented polypropylene, polyethylene, and PET, as well as paper and foil-based wrappers; more sustainable options include biodegradable or compostable films and paper alternatives.

Wrapper packaging is widely used for food items (candy, bakery goods, produce), magazines and books, consumer electronics accessories, and various household goods. It affords barrier protection against moisture and contamination, tamper evidence, and branding opportunities through printed graphics. From the production side, wrappers are selected based on product geometry, required seal, and desired shelf life; flow wrapping is popular for long, uniform items, shrink wrapping for irregular shapes, and stretch wrap for securing bundles and pallets. The process typically involves forming a wrapper around the product and applying heat or adhesive to seal, followed by inspection and cutting or reeling of finished packages.

Environmental and regulatory considerations influence wrapper packaging design. Recyclability and compostability depend on the chosen materials and the recycling stream, and many wrappers require specific handling to be accepted by facilities. Regulations may govern food-contact compliance, labeling, and safety requirements. Ongoing innovations focus on lighter-weight films, mono-material structures, and reduced packaging to address waste concerns.
