A hermetic bag is an airtight and moisture-proof storage solution designed to protect crops like grains and coffee from pests, mold, oxygen, and humidity during storage and transport.

‘Hermetic’ means completely sealed so that no air, gas, or moisture can enter or escape — ensuring a controlled internal environment.

Hermetic technology involves the use of specialized materials and sealing methods to create a barrier that prevents air, moisture, and external contaminants from affecting stored goods.

The term “hermetic” comes from ancient sealing techniques attributed to Hermes Trismegistus, symbolizing perfect airtight sealing, now used to describe advanced barrier packaging.

• Prevents pest infestations without chemicals
  
• Inhibits fungal and mold growth
  
• Preserves freshness, aroma, and quality
  
• Extends shelf life
  
• Reduces post-harvest losses

Products are packed into a specially designed, multi-layer film bag or liner. Once sealed, the oxygen inside is gradually reduced, creating a modified atmosphere that naturally preserves the contents.

Yes, most hermetically sealed bags and liners are water-resistant, preventing external moisture from entering and affecting the stored material.

Hermetic bags block the entry of air, water, insects, and contaminants. They create a low-oxygen environment that halts insect life cycles and microbial activity without chemicals.

Hermetic FIBC (Flexible Intermediate Bulk Container) bags are large-capacity, multi-layered hermetic bags designed to store bulk dry commodities like grains or coffee, combining the benefits of hermetic sealing with the volume capacity of traditional FIBCs.

Hermetic container liners are large, multi-layered liners fitted inside shipping containers to protect bulk commodities during transportation. They offer airtight protection against moisture, pests, and contamination.

Indoor hermetic bags are designed for smaller-scale or warehouse storage. They offer the same airtight and moisture-resistant properties as larger hermetic bags, ideal for smallholder farmers or in-house storage needs.

While some hermetic bags are designed for single-use to maintain peak sealing integrity, high-quality versions can be reused if they are not damaged and are properly cleaned and resealed.

Hermetic packaging is ideal for: coffee, cocoa, seeds, spices, nuts, tea leaves, dried herbs, oil seeds (soybeans, sunflower, sesame), milled rice, aromatic or pigmented rice varieties.

Yes. Hermetic bags and container liners are widely used for international shipping as they maintain product quality during long transit times and changing weather conditions.
