What Plastic Bottles Hold Up Best in Cold Weather?
Comparing HDPE, LDPE, PET, And Polypropylene Bottles And Jars For Cold Storage And Shipping
If you store or ship product through the winter, the plastic bottles you choose make a real difference, because HDPE, LDPE, PET, and polypropylene each have a different low-temperature limit. Here is how they compare, and what to check before you commit.
How Plastic Type Affects Cold Performance
Every plastic material type has a low-temperature point below which it becomes stiffer and more brittle. The figures below are typical resin-level minimum service temperatures from published references. They vary with grade, additives, and wall thickness, and they describe the plastic itself, not a tested bottle, so use them as a way to compare materials, not as a guarantee. We always recommend testing with a free sample before committing to a full production run for any application.
HDPE and LDPE: The Cold-Weather Performers
LDPE and HDPE plastic bottles are typically good down to roughly -50°C to -60°C (-58°F to -76°F), staying flexible and keeping their impact strength in freezer-like conditions, and some specialized HDPE grades go lower. Natural HDPE bottles and LDPE squeeze bottles are common choices for products stored or shipped in the cold. Learn more about HDPE plastic and LDPE plastic on our material info pages.
PET: Good Down to About -40 Degrees
PET is typically good down to about -40°C (-40°F). Below that it loses impact resistance and can become brittle. For most winter shipping and storage, that is cold enough to cover, which makes PET bottles a reasonable choice. See our PET plastic page for more.
Polypropylene: Plan for Brittleness Near Freezing
Standard homopolymer polypropylene tends to become brittle below 0°C (32°F), unless it is an impact copolymer blend made for low temperatures. Many jars and caps are molded from PP, so handle polypropylene jars gently when they are cold and test them first. See our polypropylene plastic page for more.
The Contents Still Matter
Even the most cold-tolerant plastic bottle can bulge or split if a water-based product freezes solid inside it. Leave headspace, and test your formula and bottle together. After cold storage, confirm each cap still seals; our guide to testing a cap for a proper seal before shipping shows how. Browse our plastic bottles to compare materials.
