Are Uchampak products suitable for special usage scenarios like freezing and microwaving?

For specialized needs, select paper packaging series are engineered for frozen storage and microwave heating. Safety remains our top priority, and we strongly recommend real-world testing before bulk procurement.

1. Freezer Storage Compatibility
For frozen takeout foods, we offer takeout boxes, paper bowls, and other products made from thickened paper substrates (e.g., heavy kraft paper). Through process optimization, these products enhance structural stability at low temperatures to withstand standard freezer storage and transportation. All materials comply with national food contact material safety standards.

2. Microwave Heating Compatibility
We offer a dedicated product line clearly labeled “microwave-safe,” including select paper bowls and hot beverage cups. These items utilize heat-resistant materials and safe coatings for short-term microwave heating. Note: Specific tolerance times and power levels vary by product. Always follow product instructions and test samples before bulk use.

3. Customized Consultation & Testing
If your food items (e.g., pre-made meals) require packaging suitable for both freezing and microwave heating, clearly specify this dual requirement during consultation. As your packaging supplier, we can recommend product lines with corresponding performance potential based on your food type and process. We strongly advise conducting full-process simulation testing to verify suitability.

We are committed to providing reliable takeout packaging solutions for restaurants, cafes, and similar establishments. To test the suitability of your custom French fry boxes, popcorn containers, paper bowls, or other products under specific conditions, please request samples and discuss your detailed requirements with us.
