3g Moisture Absorber Bags for Food – Food Safe Silica Gel Packets

3g Food Grade Indicating Silica Gel Desiccant Packets – OPP Packaging

Wisesorbent's 3g food-safe silica gel desiccant packets are engineered for direct contact with food, supplements, and pharmaceutical products. Packaged in breathable OPP (oriented polypropylene) material with water-based ink printing, they effectively absorb moisture to keep contents dry, fresh, and shelf-stable.

Key Features

• Food Safe OPP Packaging: Water-based ink printing on OPP film — safe for direct contact with food, medicine, vitamins, and health care products. Oil-resistant with micro-perforations for breathability.
• Indicating Color Change: Cobalt chloride-free, DMF-free orange silica gel beads turn green when moisture-saturated, providing a clear visual signal of absorption status without opening the package.
• High Absorption Capacity: Absorbs up to 40% of its own weight in moisture. Each 1g of silica gel protects up to 120 cubic inches of enclosed space — ideal for sealed containers and bulk packaging lines.
• Single-Use Design: OPP packaging is not heat-tolerant. These packets are designed for single use and should be replaced once beads turn fully green.
• Non-Toxic & Stable: Silica gel is non-combustible, non-corrosive, and chemically stable. Safe for use alongside food, medications, and sensitive materials.

Where to Use & How Many You Need

A general rule: use 1 gram of desiccant per 100–150 cubic inches (1.6–2.5 liters) of enclosed space. The 3g packet covers up to 300–450 cubic inches — a versatile size for most standard retail and food packaging applications.

• Beef jerky & dried meat bags (4–8 oz): Place 1 × 3g packet per sealed bag to prevent moisture from softening texture and reducing shelf life.
• Nuts, seeds & trail mix (8–16 oz): Use 1–2 × 3g packets per resealable bag to keep contents crisp and prevent clumping.
• Supplement & vitamin bottles (60–120 count): 1 × 3g packet per bottle maintains potency and prevents moisture-induced degradation.
• Pet treats & dry kibble bags (0.5–1 lb): 1 × 3g packet per bag keeps treats dry and palatable for longer.
• Tea canisters & coffee bags (4–8 oz): 1 × 3g packet per container preserves aroma and prevents clumping.
• Spice jars & seasoning pouches: 1 × 3g packet per container prevents caking and extends flavor shelf life.
• Ammo cans & tool boxes: 1 × 3g packet per 300 cubic inches of interior space prevents rust and corrosion.
• Camera bags & electronics cases (medium): 1–2 × 3g packets per case protects lenses, sensors, and circuit boards from humidity damage.

For larger containers or high-humidity environments, increase quantity proportionally. For smaller individual portions, consider our 1g or 2g options. For larger spaces, see our 5g packets.
