Manufactured from high‑quality, food‑grade polypropylene (PP) or high‑density polyethylene (HDPE) — both BPA‑free and odourless. The screw cap is polypropylene with an optional silicone or foam liner to improve the airtight seal and reduce contamination risk. Materials are chemical‑resistant to many common cosmetic solvents; suitable for creams, ointments, balms, lotions and pharmaceutical formulations. Capacity: 500g (approx. 500ml for product densities near water).

1. Clean and sterilize jars before first use if packaging sterile or sensitive products.
2. Pour or spoon your ointment, cream or balm into the jar, leaving recommended headspace for expansion.
3. Ensure the screw cap is closed firmly; check the liner for correct placement to maintain an airtight seal.
4. Label jars with product name, batch, date and storage instructions for compliance and traceability.
5. To clean, wash with mild detergent and warm water; dry thoroughly before refill. Avoid high‑temperature sterilization unless material specs permit.

Ideal for cosmetic manufacturers, compounding pharmacies, spas and salons, indie skincare brands, artisan formulators, lab sampling and home DIYers who require reliable ointment packaging. Suited for both retail and bulk applications, sample distribution and product testing.

Not a sterile medical device unless supplied sterile. Store jars in a cool, dry place away from direct sunlight and heat sources to maintain material integrity. Avoid prolonged exposure to strong solvents or high temperatures above the manufacturer’s recommended range; some chemicals can soften or deform plastic. Keep out of reach of children. Inspect closures regularly for wear; replace if the liner or thread becomes damaged. Follow local recycling guidance when disposing.
