Packaging materials must be moisture-proof, durable, and leak-resistant. They should not become brittle at low temperatures and must resist oil, grease, and water. Additionally, they should prevent food from absorbing odors and be easy to seal and label. Suitable materials include PVA-coated high-barrier films, low-density polyethylene (LDPE) films, polyester (PET) films, and biaxially oriented polypropylene (BOPP) films.

• Temperature Control: The packaging environment must maintain low temperatures (typically ≤ -18°C) to prevent product thawing, deformation, and bacterial growth.
• Anti-condensation Design: The alternation of hot and cold temperatures can cause frost to form inside the packaging. The equipment needs to seal the packages quickly and prevent moisture penetration.
• Material Cold Resistance: Ordinary packaging films can become brittle in low temperatures, while frozen food packaging must use low-temperature-resistant materials like PE/PA composite materials.
