18.9MM Coffee Bags Valve with Filter, Coffee Bag Air Vent, Coffee Valve One Way Degassing - HL-TA

18.9MM Coffee Bags Valve with Filter, Coffee Bag Air Vent, Coffee Valve One Way Degassing - HL-TA

Product Overview

The HL‑TA coffee bags valve is engineered for roasted coffee packaging, allowing CO₂ to escape while blocking oxygen and contaminants. This ensures freshness, prevents swelling, and maintains product stability across the entire shelf life.

• Application: Coffee bags, powder packaging, food, chemical, and personal care.
• Core function: One‑way degassing to protect aroma and prevent oxidation.
• Compatibility: Works with stand‑up pouches and gusset bags from 5g to 5kg.
• Keyword integration: Optimized for “coffee bags valve” without overuse.

Key Features of Coffee Bags Valve HL‑TA

The HL‑TA coffee bags valve uses a filtered one‑way structure that ensures smooth degassing while preventing dust and oil contamination. Its durable PE construction maintains stability during heat sealing and long‑term storage.

• One‑way degassing: Releases CO₂ efficiently to avoid swollen bags.
• Integrated filter: Blocks fine powder and oils from entering the valve.
• High compatibility: Suitable for laminated films such as PET/AL/PE and PP.
• Durable structure: PE housing ensures long service life.
• Food‑grade safety: Meets international packaging standards.

Technical Specifications

The HL‑TA coffee bags valve is precisely engineered for mainstream coffee packaging, ensuring consistent performance and reliable sealing.

How Coffee Bags Valve Works

The coffee bags valve uses a low‑pressure membrane system that opens when CO₂ builds up inside the bag. Once pressure drops, the membrane closes to prevent oxygen from entering, preserving aroma and freshness.

• Degassing mechanism: CO₂ pushes the membrane open for controlled release.
• Anti‑backflow: Outside air cannot enter the coffee bag.
• Filter function: Blocks powder and oil particles from clogging the valve.
• Roasted coffee protection: Prevents oxidation and flavor loss.

Extended Technical Characteristics of Coffee Bags Valve HL‑TA

The HL‑TA coffee bags valve is engineered with a precise one‑way structure, optimized materials, and controlled cracking pressure to ensure stable CO₂ release and long‑term freshness. Its design supports consistent performance across different bag sizes and laminated films.

• Purpose: Allows roasted coffee to release CO₂ while preventing oxygen and contaminants from entering, keeping the product fresh and preventing bag swelling.
• Type: One‑way check valve composed of a valve body and membrane; common structures include diaphragm, multi‑chamber, and needle‑pierceable designs.
• Materials: Plastic housing (PP/PE) combined with silicone or TPE membranes; some versions include felt or nonwoven filter layers for added protection.
• Flow rate / cracking pressure: Low cracking pressure (<50–100 mbar) ensures CO₂ escapes easily; performance varies by membrane thickness and valve geometry.
• Filtration: Integrated porous filter layer blocks fine particulates and oils, maintaining clean airflow and preventing clogging.
• Orientation & mounting: Surface‑mounted or heat‑sealed onto laminated films; recommended placement is the upper front third of the bag with correct outward orientation.
• Packaging compatibility: Designed for PET/AL/PE, PP, and other laminated structures; available with heat‑sealable flange or adhesive backing.
• Size options: Common external diameters range from 6–14 mm; selection depends on bag capacity and required degassing rate.
