PVC / PVDC Plastic Cling Wrap vs. Anchor Hocking Glass Storage Containers

Materials

• Polyvinyl chloride (PVC) or polyvinylidene chloride (PVDC)

Common claims

• Clings on contact
• Airtight seal
• Microwave safe

Concerns / watch-outs

• PVC cling wraps contain plasticizers (some phthalates) that can migrate into fatty foods
• Microwaving fatty foods in contact with PVC wrap increases migration risk

Notes

Avoid direct contact with fatty foods and microwave use. Beeswax wraps, silicone lids, or reusable containers are better alternatives for regular use.

Cleaner alternatives

• beeswax food wrap
• silicone storage bag
• borosilicate glass container

Materials

• Tempered glass
• Plastic or metal lids

Common claims

• Made in USA
• Oven and microwave safe
• Non-porous

Concerns / watch-outs

• Tempered glass (not borosilicate); avoid sudden temperature changes like freezer-to-oven
• Check lid materials; metal lids are microwave-unsafe and plastic lids vary in quality

Notes

Anchor Hocking is a solid, US-made glass container brand. The glass itself is inert; choose lids carefully for a complete low-tox setup.

Cleaner alternatives

• borosilicate glass container
• pyrex glass containers
