Knowra Food packaging Food packaging Food packaging comprises materials and containers that protect, store, transport, and present food. It helps control contamination, damage, and changes in quality between production and consumption.
Oxygen transmission rate : The amount of oxygen that passes through a material over time under specified conditions. It measures how effectively a package limits oxygen-driven rancidity, discoloration, and spoilage.
Food spoilage : The physical, chemical, or microbial deterioration that makes food undesirable or unsafe. Packaging choices target the particular processes that spoil each food.
Retort pouch : A flexible heat-resistant package used to sterilize and store food commercially. It withstands retort processing while reducing package weight compared with metal cans.
Food waste : Food intended for consumption that is discarded, lost, or left uneaten. Protection and portioning can prevent waste, while excess packaging can create other costs.
Reusable packaging : Packaging designed to be returned, cleaned, and used repeatedly. It contrasts with single-use formats, but requires effective return and cleaning systems.
Water vapor transmission rate : The rate at which water vapor permeates a material under specified conditions. It predicts moisture loss or uptake that can soften, dry, or stale packaged foods.
Food contact materials : Materials and articles intended to contact food during production, storage, or serving. Food packages are regulated as food contact materials because substances can migrate into food.
Tetra Pak : A brand of packaging systems, especially cartons for liquid foods and beverages. Its aseptic cartons combine barrier layers to protect shelf-stable drinks.
Packaging waste : Discarded packaging materials generated after products are used. Food packaging is a major source of consumer packaging waste and recycling challenges.
Single-use packaging : Packaging designed for one use before disposal or recycling. Its convenience and hygiene differ from reusable systems that depend on multiple cycles.
