LDPE Zip-Lock Plastic Bag (#4) vs. Anchor Hocking Glass Storage Containers

Materials

• Low-density polyethylene (LDPE, recycling #4)

Common claims

• BPA-free
• Leakproof zipper
• Freezer safe

Concerns / watch-outs

• Single-use at scale generates significant plastic waste
• LDPE can release additives when in contact with fatty or hot foods

Notes

LDPE is one of the safer single-use plastics, but the environmental footprint and single-use nature make reusable alternatives a better everyday choice.

Cleaner alternatives

• silicone storage bag
• stainless steel food container
• beeswax food wrap

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
