Clay 5g — OPP Film — Blue

CEMACOSG's Clay Montmorillonite 5g Blue OPP Film sachet is a natural mineral desiccant that performs at its best between 20–50°C — outperforming silica gel in tropical warehouse conditions at moderate relative humidity of 50–80%. Clay achieves 25–30% moisture absorption by weight and sustains capacity more reliably than Type A silica gel at temperatures above 40°C, where silica gel performance declines noticeably.

Technical Specifications

• Net weight: 5 g (tolerance ±5%)
• Composition: Montmorillonite (calcium bentonite) — natural mineral clay, non-toxic, DMF-free
• Moisture absorption: 25–30% by weight at 25°C / RH 90% (ASTM D5790)
• Optimal operating range: 20–50°C, RH 30–80% — more stable capacity than silica gel above 40°C
• Packaging material: Virgin kraft (70 g/m²) + outer OPP film, blue — 1–4 colour flexo print
• Standards: FDA 21 CFR 182.2727 (GRAS) · ISO 9001:2015 · HACCP
• Shelf life: 18 months (sealed, ≤ 30°C) — not regenerable

Practical Applications

• Tropical dry-food products: Cashews, palm sugar, tea and dried nuts — clay is food-grade GRAS under FDA 21 CFR 182.2727, safe for indirect food contact, maintaining internal RH below 50% and preventing caking and off-flavour absorption. Clay outperforms silica gel in Southern Vietnamese summer warehouses running at 35–45°C.
• Pharmaceuticals & nutraceuticals in bottles: Tablets or capsules in HDPE bottles or folding cartons — 5g clay per 100g of product is the standard loading in the industry. Clay does not liquefy when saturated (unlike CaCl₂), eliminating the risk of liquid leakage into the product.
• Leather goods & footwear for intra-ASEAN export: Unconditioned truck and short-sea routes (Vietnam–Thailand–Indonesia) — 5g clay per box manages humidity effectively during 3–5-day journeys where truck internal temperatures commonly reach 45–50°C in daytime.
