Microwave-Safe Aluminum Foil Bags use food-grade aluminum foil + PET/PE composite film as the base material, designed with metal-free connector technology (to avoid sparking during microwave heating). They can withstand microwave heating at 120-150°C, and corely combine the high oxygen/moisture barrier properties of aluminum foil with the convenience of microwave heating—no need to transfer contents to a container for direct heating. These bags are widely used in food scenarios requiring "storage + rapid heating," such as pre-cooked meals (braised pork, curry rice), instant rice, cooked food packaging (marinated meat, roasted chicken), and baby food, suitable for convenient dining needs at home, offices, and outdoor camping.
Compared with regular non-microwaveable aluminum foil bags and ordinary PE microwave bags, their core performance is significantly improved:
- High-temperature safety is increased by 40%-60%: Regular aluminum foil bags contain metal parts (e.g., rivets), which easily spark in microwaves and pose safety risks. This bag’s metal-free design is safely compatible with mainstream household microwaves (700-1000W), with no deformation or harmful substance release after heating;
- Heating uniformity is enhanced by 35%-55%: The aluminum foil composite structure disperses microwave energy, avoiding the "local overheating (e.g., burnt edges) and underheated center" issue of ordinary PE microwave bags, achieving over 90% uniform heating of food;
- Shelf life of contents is extended by 50%-70%: The composite structure of aluminum foil (oxygen barrier) + PE (moisture barrier) has an oxygen transmission rate 60% lower and a moisture transmission rate 50% lower than ordinary PE microwave bags. The refrigerated storage period of pre-cooked meals extends from 3 days to 5-6 days, and the oxidative spoilage rate of cooked food decreases by 85%;
- Leak-proof sealing is improved by 30%-50%: The bag mouth seal is reinforced with high-temperature treatment, which is less likely to crack due to internal steam pressure during microwave heating (sealing clips, if any, should be removed), with a liquid leakage rate 70% lower than ordinary PE microwave bags;
- Heat retention is boosted by 45%-65%: The aluminum foil material reduces heat loss, keeping food warm for 20-30 minutes longer than ordinary PE bags after heating, suitable for outdoor scenarios without continuous heating conditions.
Compared with regular versions, it additionally has three core advantages:
- Integrated "aluminum foil protection + microwave heating" functions: Regular non-microwaveable aluminum foil bags only support oxygen-free storage and require transfer to bowls for heating; ordinary PE microwave bags lack aluminum foil’s barrier properties, leading to easy food oxidation—this bag solves the pain points of "long-term freshness" and "convenient heating" simultaneously, serving as a functional upgrade of both;
- Food-grade safety details: The base material uses food-contactable aluminum foil and eco-friendly composite adhesive, with no odor or heavy metal leaching after microwave heating. It meets food contact material safety standards (e.g., GB 4806), making it safer than ordinary low-cost microwave bags;
- Strong scenario compatibility: It supports both refrigeration (-18°C to room temperature) and microwave heating, eliminating the need for repeated food transfer; the bag surface can be printed with heating instructions (e.g., "Heat on medium-high for 2 minutes") and nutrition fact tables, adding "usage guidance" value beyond regular aluminum foil bags, suitable for FMCG retail and home use.
