22.4mm Coffee Degassing Valve Without Filter for 500g–2kg Bags HL-TC

22.4mm Coffee Degassing Valve for 500g–2kg Bag Applications Guide

HL-TC helps coffee packers manage post-roast carbon dioxide release without relying on a separate degassing period before packaging. It is also suitable for selected feed and fermented-product packaging projects where gas release is required.

Why a 22.4mm Coffee Degassing Valve Matters for Larger Bags

Freshly roasted coffee beans continue releasing carbon dioxide after packing. When that gas remains trapped inside a sealed pouch, the package may expand, lose its intended shape, or create pressure during storage and transport. The HL-TC coffee degassing valve provides a controlled one-way gas outlet for 500g to 2kg coffee bags.

Its 22.4mm inner diameter is intended for projects that need a larger valve format than smaller coffee pouch designs. The filter-free configuration is suited to whole coffee beans and other granulated contents where a filter layer is not required for the selected filling material.

How the One-Way Valve Supports Coffee Packaging

The valve is integrated into laminated flexible packaging and operates in response to pressure inside the pouch. As roasted coffee beans release CO₂, pressure can open the valve path and allow gas to leave the bag. The one-way design then helps reduce reverse airflow into the package.

• Helps release carbon dioxide generated after coffee roasting
• Helps reduce pouch swelling caused by internal gas pressure
• Helps limit oxygen and water-vapor ingress during sealed storage
• Supports coffee packaging operations that need earlier filling after roasting
• Works with laminated bags used for coffee beans and selected granulated products

Product Specifications

What to Confirm Before Selecting HL-TC

Valve selection should be based on the product being packed, pouch format, fill weight, and packaging process. A 22.4mm coffee bag one-way valve is not automatically the right choice for every coffee pouch, especially when the filling material contains fine powder or when the package uses a smaller panel area.

• Confirm whether the packaged product is whole coffee beans, ground coffee, feed, or another granulated material
• Confirm the finished bag capacity, especially for projects between 500g and 2kg
• Check the available valve placement area on the pouch panel
• Confirm whether a filter-free valve is appropriate for the filling material
• Provide the pouch material structure and sealing process for application review

OEM and ODM Options

Hanle Packing can review OEM and ODM requirements for HL-TC coffee degassing valve projects based on the pouch format, filling material, target quantity, and technical specifications. The standard HL-TC configuration is a white, filter-free PE valve with a 22.4mm inner diameter for 500g to 2kg packaging projects.

• Size Review: Valve dimensions can be assessed against the pouch panel area and intended packaging format
• Color Requirements: Color options can be reviewed according to order quantity and project specifications
• Filter Configuration: Filter-free or filtered valve requirements can be assessed according to the filling material
• Sample Assessment: Sample arrangements can be discussed for pouch compatibility and packaging-line evaluation
• Bulk Packing: Carton, pallet, and project-specific export packing requirements can be confirmed before production

Choosing Between HL-TC and HL-TAW Coffee Valves

HL-TC and HL-TAW are both filter-free one-way valves designed for roasted coffee beans and other granulated products. Their main differences are valve diameter, height, and recommended package-capacity range. Selection should be based on the pouch format, available valve placement area, filling material, and packaging process.

HL-TC is intended for projects that require a 22.4mm valve format for coffee bags from 500g to 2kg. For packaging projects that need a 19.8mm valve or a broader nominal capacity range, review the HL-TAW coffee valve. Final valve selection should be confirmed against the actual pouch design, panel space, filling material, and packaging conditions.

Standard Configuration and Project Requirements

HL-TC is supplied as a standard white, 22.4mm PE coffee degassing valve without a filter. This standard configuration is intended for buyers that require a defined valve size and a filter-free structure for larger coffee bags or granulated-product pouches.

For projects involving different valve dimensions, filter requirements, colors, packaging configurations, or application conditions, Hanle Packing can review the requirement before quotation. Feasibility should be confirmed according to the target packaging material, filling product, quantity, and technical specifications.

Applications for Coffee and Granulated Product Packaging

This coffee bag one-way valve is designed primarily for roasted coffee bean packaging. Its 22.4mm format can also be considered for laminated pouches containing other products that release gas during storage or processing.

• Roasted coffee beans in 500g, 1kg, and 2kg packaging formats
• Flat-bottom coffee bags for retail, wholesale, and foodservice supply
• Stand-up zipper pouches for coffee bean distribution
• Fermented feed packaging where controlled gas release is required
• Pet food, livestock feed, poultry feed, fish feed, and shrimp feed packaging, subject to packaging compatibility review

Typical Procurement Scenario

A coffee packaging buyer sourcing valves for 1kg flat-bottom bags needs to package roasted beans shortly after roasting while keeping the finished bags stable during warehouse handling and export transport.

Buyer Requirement: The buyer requires a filter-free valve for whole coffee beans, a size appropriate for a larger pouch format, and bulk packing suitable for integration into an established flexible-packaging supply chain.

Solution: Hanle Packing recommends the HL-TC 22.4mm coffee degassing valve after confirming the 1kg bag format, laminated pouch structure, whole-bean filling material, and the buyer’s required purchase quantity. The valve is supplied in its standard white PE configuration with carton and pallet packing.

Result: The buyer has a defined valve specification for evaluation with the selected bag structure and filling process. Final order approval can then be based on compatibility checks, sample assessment where required, and the confirmed production schedule.

Frequently Asked Questions

Is HL-TC suitable for ground coffee?

HL-TC is a filter-free coffee degassing valve and is primarily positioned for whole coffee beans and other granulated products. For ground coffee or powder-containing products, confirm whether a valve with a filter is more suitable for the filling material and packaging process.

What bag size is this 22.4mm coffee bag one-way valve designed for?

HL-TC is recommended for flexible packages with capacities from 500g to 2kg. Final suitability also depends on bag dimensions, panel space, material structure, and the amount of gas released by the packaged product.

Can this coffee degassing valve be used on stand-up and flat-bottom bags?

Yes. HL-TC is intended for laminated packaging formats such as stand-up zipper pouches and flat-bottom bags, provided the valve placement and packaging process are compatible with the pouch structure.

What is the minimum order quantity for HL-TC?

The standard MOQ is 200,000 sets. For project-specific requirements, provide the expected quantity and product specifications for quotation review.

What information is needed to assess a project requirement?

Please provide the packaging application, product being filled, bag type, package capacity, expected order quantity, pouch material structure, and whether a filter-free valve is required. These details help confirm whether HL-TC is appropriate for the project.
