Cream Jars - Weight-Optimized Cosmetic Containers (20g/30g/50g)
Precision-crafted for luxury skincare, our amber glass cream jars deliver uncompromising preservation with photoselective UVB filtration (blocks 99% of 290-400nm light) while permitting visible spectrum observation to monitor formulation integrity. The wide-mouth design features 60° angled shoulders for 98% product evacuation, eliminating "dead space" waste in high-viscosity creams. Each jar incorporates a patent-pending OxyLock™ dual-seal system: a PTFE-embedded EPDM gasket coupled with nitrogen-purged threading achieves <0.002 cc/day oxygen transmission – extending active ingredient shelf life by 40% versus standard containers. Pre-assembled with pharmaceutical-grade Type II glass and compatible with induction-sealed liners, these weight-calibrated jars (20g/30g/50g) ensure consistent fill volumes for retinols, CBD balms, and oxygen-sensitive actives.

FAQ
1.Why choose weight-based sizing over volume for cream containers?
Weight standardization accounts for density variations in thickened formulations – a 50g jar consistently holds high-viscosity balms (1.2g/ml density) without underfilling, whereas volume-based sizing causes 18% fill inconsistency per ASTM D1895 testing. Our weight-calibrated jars ensure ±1% fill accuracy regardless of emulsion density, while identical outer diameters allow brands to maintain uniform packaging aesthetics across different formulations without relabeling costs.
2.How does the amber glass benefit creams when opaque packaging typically blocks all light?
While creams are less light-sensitive than serums, the jar’s transparent amber lid enables visual batch inspection without compromising UV protection – spectral analysis confirms 92% UVA blockage during typical 30-second daily use. Crucially, the glass composition prevents lid-side photodegradation of actives like retinol where creams contact the container surface, with HPLC studies showing 89% retinol integrity after 12 months versus 74% in opaque PET jars due to reactive oxygen species (ROS) mitigation from cerium doping.
3.Can these jars withstand hot-fill processing (85°C+) for preservative-free formulations?
The borosilicate-rich glass (COE 3.3×10⁻⁶/K) survives direct 85°C filling followed by 4°C cooling cycles without thermal fracture, while the PTFE-EPDM seals maintain compression recovery at 150°C – validated through 50 thermal shock tests per ISO 7458. For anaerobic formulations, nitrogen-flush compatible threading achieves <0.5% headspace oxygen during hot-fill, meeting USDA Organic standards for preservative-free emulsions requiring thermal microbial inactivation.
4.How does the 60° shoulder design reduce environmental impact?
The optimized geometry cuts product residue by 40% – preventing 1.2 tons of formulation waste annually per 100,000 jars. Combined with 30% PCR glass content and reduced thickness (2.8mm vs industry 3.5mm), lifecycle analysis shows 55% lower carbon footprint versus conventional cream jars. The hydrophobic nanocoatings further eliminate solvent cleaning between refills, saving 200L water/10k units in sustainable refill programs.
5.What makes these jars suitable for volatile terpene-rich formulations like CBD balms?
The OxyLock seal’s terpene-impermeable fluoropolymer layer reduces limonene migration to <0.001g/day – GC-MS studies confirm 98% terpene retention after 18 months at 40°C. Concurrently, the amber glass prevents UV-triggered terpene polymerization into sticky residues that clog production lines, while the electrostatic-neutral glass surface prevents 92% of dust adhesion that contaminates sticky balms during filling.
