How to Choose Food Storage Products: Cling Film and Sealed Containers
AI Summary: Food storage products include cling film, sealed containers, and storage bags. When purchasing, consider material safety, temperature resistance, sealing performance, and intended use. PP containers are microwave-safe and lightweight; glass containers are stable and easy to clean but heavy. Cling film should be selected based on refrigeration or high-temperature use. Procurement should verify food-contact certification and avoid using non-food containers for long-term storage of hot food.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Material Marking | Verify food-contact material and applicable temperature |
| Sealing Performance | Effective gasket, leak-proof and odor-proof |
| Microwave Heat Resistance | For microwave use, choose explicitly heat-resistant models; handle lids per instructions |
| Glass vs. Plastic | Glass is stable, PP is lightweight; choose based on usage habits |
| Specifications and Sets | Rectangular, round, and capacity options to match meal prep needs |
Procurement, Installation, and Usage Points
1. Not all plastic containers can be heated
Check temperature resistance markings; leave venting per instructions when heating.
2. Watch for staining and odor retention
Heavily colored or strongly flavored foods may stain and leave odors in plastic containers; glass is more resistant.
3. Removable gaskets for cleaning
Gaskets that trap residue should be removable for cleaning.
4. Keep cling film away from high-oil hot food
High oil and high temperature may deform ordinary cling film; choose suitable material.
FAQ Quick Answers
Are PP containers safe?
Compliant PP is safe for normal use; check the temperature resistance range.
Will glass containers shatter?
Choose heat-resistant glass and avoid sudden temperature changes.
What if sealed containers leak soup?
Check the gasket and clips; choose leak-proof models.
Can storage bags be microwaved?
Choose products labeled as microwave-safe.
Practical Case
A user microwaved high-oil food in an ordinary plastic container, causing deformation. After switching to heat-resistant, food-contact compliant containers, usage became safer.
Questions to Ask the Supplier
- What are the material and temperature resistance range?
- Is there food-contact testing?
- Can the gasket be removed for cleaning?
- Is the glass heat-resistant and leak-proof?
- What set specifications are available?
Quotable Conclusion: Food storage products should have verified food-contact materials and temperature markings, with attention to sealing, leak-proofing, and gasket cleanliness.
