Which plastic food storage container is best?

1. Polypropylene—Best overall performance
High melting point and heat resistance: PP has a melting point of approximately 165°C. It maintains its shape even when heated in a microwave or filled with boiling water, preventing deformation or leakage.
Food-grade safety: It complies with food contact material standards such as GB4806.7, has extremely low migration, and is harmless to the human body during long-term use.
Chemically inert: It exhibits excellent corrosion resistance to common food ingredients such as acids, alkalis, and oils, and does not produce harmful chemical reactions.
Recyclable: PP is a recyclable plastic with a mature recycling chain, meeting sustainable development requirements.
2. High-density polyethylene—Suitable for room-temperature dry foods
Low-temperature toughness: It maintains good toughness at low temperatures, making it suitable for refrigerated or room-temperature storage of grains, dried fruits, and milk powder.
Barrier properties: It provides a certain barrier to moisture and oxygen, extending the shelf life of dry goods.
Acid and alkali resistance: It has good resistance to most acidic and alkaline seasonings and sauces, making it suitable for packaging sauce bottles or seasoning packets. Cost Advantage: Relatively low raw material costs and mature production processes make it suitable for mass production of disposable packaging.
3. Polyethylene Terephthalate - Transparent Disposable Packaging
High Clarity: Excellent optical properties allow for clear display of the color and texture of beverages or cold foods, enhancing the product's visual appeal.
Gas Barrier: Excellent barrier properties against carbon dioxide and oxygen, suitable for maintaining the freshness of carbonated beverages, juices, and other products.
Disposable: Suitable for single-use applications such as cold drinks and ice cream cups, avoiding material degradation caused by repeated heating.
Recycling System: PET has a high recycling rate both domestically and internationally, aligning with the trend toward environmentally friendly packaging.
4. Materials Not Recommended: Polyvinyl Chloride: Potentially releases chlorides when exposed to high temperatures or oils, posing potential health risks.
BPA-Containing Polycarbonate: BPA may disrupt the endocrine system, making it particularly unsuitable for food or beverage packaging.
Are there any safe plastic food containers?
1. PP - The Safe Choice
Microwave Resistant: Microwave-safe and low in harmful substances. Food-Grade Certification: Most PP containers are FDA and EU certified for food contact.
Multifunctional Lid Design: The sealing lid is made of the same material or food-grade silicone to prevent leaks and keep food fresh.
2. HDPE - Suitable for refrigerated and dry goods
Low-Temperature Resistance: Resists brittle cracking in refrigerator or freezer environments, ensuring packaging integrity.
Chemical Inertness: Non-corrosive to common condiments such as acids, alkalis, and salt, making it suitable for packaging sauces or seasoning powders.
Environmental Protection: High recyclability, meeting the sustainable development goals of green packaging.
3. PET - Disposable Transparent Packaging
Gas Barrier: Effectively preserves the bubbles in carbonated beverages and the flavor of juices.
Disposable Safety: Suitable only for cold or room-temperature beverages to avoid material degradation caused by repeated heating.
Lightweight: Lighter than glass containers, reducing transportation energy consumption.
4. Compliance with National Standards
GB4806.7: PP, HDPE, and PET are explicitly listed as plastic materials permitted for food contact. ISO9001/ISO22000 Quality Systems: Many manufacturers have achieved these certifications, ensuring that raw material sourcing, production processes, and finished product testing meet food safety requirements.
