Moisture Barrier for Hygroscopic Products

Moisture barrier liners are made from Polypropylene materials that have inherently low moisture permeability. Common materials include

• Foil laminatesAluminium foil combined with other materials such as plastic films (e.g., PET, PE) to create a barrier against moisture.
• Metallized filmsPlastic films with a thin layer of metal (such as aluminium) deposited on them to enhance moisture resistance.
• Specialized polymersCertain polymers like ethylene vinyl alcohol (EVOH) or polyvinylidene chloride (PVDC) provide excellent barrier properties against gases & moisture.

Moisture barrier liners are used in various industries where protecting products from moisture is critical

• Food packagingEspecially for sensitive food products like snacks, cereals, & powders.
• PharmaceuticalsTo protect medications & sensitive chemicals from moisture degradation.
• ElectronicsPreventing moisture damage to sensitive electronic components during shipping & storage.
• Industrial productsSuch as powders, granules, & chemicals that can absorb moisture & clump or degrade.

• Moisture ProtectionEffective in preventing moisture ingress, which can lead to degradation, clumping, or contamination of products.
• Barrier PropertiesProvides a reliable barrier against humidity & moisture vapor transmission.
• CompatibilityCan be tailored to suit different types of packaging formats, including bags, liners, pouches, & containers.

• Insert linersPlaced inside containers such as drums, boxes, or totes to protect the contents.
• Laminated linersIntegrated into multi-layer packaging films or bags to enhance moisture resistance.
• Barrier bagsEntire bags made from moisture barrier materials, used for direct packaging of sensitive products.

• CostMoisture barrier liners can be more expensive than standard packaging materials due to their specialized properties.
• EffectivenessProper sealing & handling are crucial to ensure the liner maintains its barrier properties throughout storage & transport.
• Environmental impactSome barrier materials may not be easily recyclable, so consideration of environmental impact is important.

Moisture barrier liners are an essential tool in packaging sensitive products where moisture control is critical to maintaining product quality & shelf life. They provide a reliable solution to protect against moisture-related damage & ensure products reach consumers in optimal condition.
