LDPE Zip-Lock Plastic Bag (#4)

⚠️ USE WITH CAUTION

Storing snacks, sandwiches, and portioned ingredients

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

Tritan BPA-Free Water Bottle

⚠️ USE WITH CAUTION

Lightweight, durable everyday drinking bottle

Materials

Tritan copolyester (BPA-free)

Common claims

BPA-free
Shatterproof
Clear as glass

Concerns / watch-outs

BPA-free Tritan has faced scrutiny over potential estrogenic activity from alternative plasticizers
Plastic-on-plastic contact with acidic beverages or hot liquids should be avoided

Notes

Better than polycarbonate or BPA-containing plastics, but glass or stainless are more definitively inert. For cold water use, the risk is low. Avoid hot beverages.
