HDPE chemical bottles resist most acids, alkalis, detergents and water-based chemicals, which makes them the standard for chemical packaging. They are not recommended for strong oxidisers or aromatic and chlorinated solvents without a barrier layer. Always test your formulation in the bottle before bulk use.
HDPE is the most common plastic for chemical bottles because it resists most acids, alkalis and water-based chemicals and does not shatter like glass. But not every chemical suits HDPE, and the bottle, cap and liner must work together.
Which chemicals is HDPE good for?
| Chemical group | HDPE suitability |
|---|---|
| Dilute and many strong acids (e.g. hydrochloric, phosphoric) | Generally good |
| Alkalis (e.g. caustic soda solutions) | Generally good |
| Water-based agrochemicals and fertilisers | Good |
| Detergents and disinfectants | Good; use stress-crack resistant grades |
| Aromatic and chlorinated solvents | Not recommended in plain HDPE; consider a barrier bottle and test first |
| Strong oxidisers (e.g. concentrated nitric acid) | Not recommended |
This table is general guidance only. Always test with your own formulation.
Popular chemical bottle sizes
- 1 litre chemical bottle and 2.5 litre chemical bottle with heavy walls for laboratory and industrial chemicals
- Round bottles from 100 ml to 1 litre for agrochemicals and cleaners
- Black cap bottles for chemicals and lubricants
- Jerry cans from 500 ml to 10 litres for larger volumes
- The 250 ml 4-layer bottle for solvent-based products that need a barrier
Caps and liners for chemicals
- Inner plug + screw cap: simple and strong for most liquids.
- Induction-seal wad: a welded foil seal for leak-proof transport and tamper evidence.
- Vented liner: for products that release gas, such as some peroxide solutions.
How to test compatibility
- Fill sample bottles with your chemical and close them as you would in production.
- Weigh them, then store some at room temperature and some in a warm place (for example 40–50 °C) for 2–4 weeks.
- Check weight loss, bulging or collapsing walls, cracks, leaks and colour change.

Frequently asked questions
Is HDPE safe for chemicals?
For most acids, alkalis and water-based chemicals, yes. Strong oxidisers and many solvents need a different material or a barrier bottle.
What sizes are HDPE chemical bottles?
Common sizes are 100 ml to 1 litre bottles, heavy-wall 1 litre and 2.5 litre chemical bottles, and jerry cans up to 10 litres.
How do I test chemical compatibility?
Fill samples, store some warm for 2–4 weeks and check for weight loss, deformation, cracks and leaks.
