PP (Polypropylene): PP is one of the most commonly used plastics in food packaging, featuring high temperature resistance (around 120℃), low temperature resistance (down to -30℃), non-toxicity, odorlessness, moisture resistance, and oil resistance. Small plastic food boxes produced by Nanjing Xinda Plastic Products Co., Ltd. are made of pure PP material with a wall thickness of 2-3mm, suitable for holding liquid or semi-solid foods such as sauces and soups.
PET (Polyethylene Terephthalate): PET has high transparency and is often used to make transparent food boxes or beverage bottles. It has good impact resistance and chemical resistance, but is not heat-resistant (generally not exceeding 70℃).
PS (Polystyrene): PS is often used to make disposable lunch boxes; it is low-cost and lightweight, but has poor temperature resistance (generally not exceeding 90℃) and is not suitable for holding oily foods.
Paper Products: Paper food boxes are environmentally friendly and biodegradable, commonly used for packaging dry foods such as pastries and mooncakes. The food packaging boxes for donkey-hide gelatin cakes produced by Anhui Heyi Packaging Co., Ltd. are made of special paper and support processes such as hot stamping and four-color printing, making them suitable for high-end gift packaging.
Aluminum foil material: Aluminum foil food boxes have excellent barrier and heat insulation properties, and are often used for takeout packaging or foods that require high-temperature heating.
Biodegradable materials: Such as PLA (polylactic acid), which are environmentally friendly and biodegradable, but more expensive, suitable for scenarios with high environmental protection requirements.
