19.8mm Coffee Valve Without Filter for Flexible Packaging | HL-TAW

19.8mm Coffee Valve for Flexible Pouch Degassing Applications

HL-TAW is a filter-free one-way coffee valve designed for laminated pouches containing roasted coffee beans and selected granulated products. With a 19.8mm inner diameter and a 5.7mm height, it gives packaging buyers a defined valve format for stand-up pouches, zipper bags, and bottom gusset packaging.

The valve helps manage gas generated after coffee roasting without requiring the package to remain open. It is suitable for projects with packaging capacities from 5g to 5kg, subject to confirmation of the pouch structure, filling material, valve placement area, and packaging process.

Why a 19.8mm Coffee Valve Is Used in Flexible Pouches

Roasted coffee beans continue to release carbon dioxide after they are packed. If gas pressure builds inside a fully sealed pouch, the bag can expand and become difficult to handle during storage, transport, or retail display. The HL-TAW coffee valve provides a one-way path for gas to exit the package.

Its filter-free design is intended for whole coffee beans and other granular contents. Buyers should evaluate the material being filled before choosing a valve without a filter, particularly where fine powder or dust may be present inside the pouch.

• Supports the release of carbon dioxide from roasted coffee bean packaging
• Helps control internal gas pressure in sealed flexible pouches
• Helps reduce reverse airflow into the package after gas is released
• Works with common laminated pouch formats used for coffee packaging
• Provides a standard 19.8mm valve option for projects with defined pouch-panel space

How the HL-TAW One-Way Degassing Valve Works

The HL-TAW is installed on the packaging material and responds to the pressure difference between the inside and outside of the pouch. Carbon dioxide released by the packed product creates internal pressure, allowing gas to move outward through the valve structure.

When internal pressure decreases, the one-way configuration helps limit outside air from flowing back into the package. This operating principle makes the valve suitable for roasted coffee packaging, where gas release and protection from external oxygen are both relevant considerations.

Product Specifications

What to Check Before Selecting a Filter-Free Coffee Valve

A coffee valve should be selected according to the actual package design rather than by valve diameter alone. The product inside the bag, filling weight, pouch material, sealing method, available panel space, and expected storage conditions can all affect the suitability of a valve model.

• Confirm whether the package contains whole coffee beans, granules, feed, or another gas-releasing product
• Confirm that a filter-free valve is suitable for the product being filled
• Check the pouch panel area available for a 19.8mm valve format
• Provide the bag type, fill weight, and laminated material structure for review
• Confirm the required purchase quantity and standard or project-specific packing requirements

OEM and ODM Options

Hanle Packing can review OEM and ODM requirements for HL-TAW coffee valve projects according to the pouch structure, product application, expected order quantity, and packaging specifications. The standard HL-TAW is a white, filter-free PE valve with a 19.8mm inner diameter for flexible coffee bags and other granulated-product pouches.

• Valve Format: Valve dimensions can be reviewed against the available pouch panel area and bag structure
• Appearance Review: Color and packaging requirements can be discussed according to order quantity and project needs
• Application Matching: Filter configuration can be reviewed according to whether the package contains coffee beans, powder, or other granulated products
• Trial Support: Sample arrangements can be evaluated for pouch matching and application assessment before bulk procurement
• Export Packing: Inner bag, carton, pallet, and other packing requirements can be confirmed before shipment

Choosing Between HL-TAW and HL-TC Coffee Valves

HL-TAW and HL-TC are both filter-free one-way degassing valves for roasted coffee beans and other granulated products. The main difference is their valve dimension and profile, so selection should be based on the pouch design and the technical requirements of the packaging project.

HL-TAW may be considered when a project requires a 19.8mm valve format and broad packaging-capacity compatibility. For coffee bags that require a 22.4mm valve format for 500g to 2kg packaging, the HL-TC coffee degassing valve is available for evaluation. Final selection should be based on pouch dimensions, valve placement area, filling material, and packaging conditions.

Standard Configuration and Project Requirements

HL-TAW is supplied as a standard white PE coffee valve with a 19.8mm inner diameter and a filter-free structure. This configuration is intended for buyers looking for a defined valve specification for flexible coffee pouches and other packaging applications involving granulated contents.

For a project that requires a different diameter, color, filter arrangement, packaging method, or application condition, Hanle Packing can review the technical requirement before quotation. Product suitability should be confirmed against the packaging material, filling product, order quantity, and requested specifications.

Applications for Coffee and Granulated Product Packaging

The HL-TAW coffee valve is primarily intended for roasted coffee beans packed in laminated flexible bags. Its one-way degassing function can also be assessed for other packaging applications in which granulated products create gas pressure after filling or during storage.

• Roasted coffee bean pouches for retail and wholesale packaging
• Stand-up coffee bags with zipper closures
• Bottom gusset bags for coffee bean distribution
• Coffee packaging projects from small-format packs to larger supply bags
• Fermented feed, pet food, livestock feed, poultry feed, fish feed, and shrimp feed packaging, subject to compatibility review

Typical Procurement Scenario

A flexible packaging converter requires a standard coffee valve for several roasted coffee bean pouch projects supplied to regional coffee brands. The converter uses stand-up zipper bags and bottom gusset bags in different fill weights and needs a consistent valve specification for project evaluation.

Buyer Requirement: The buyer needs a filter-free valve for whole beans, a 19.8mm format suitable for the available pouch panel area, and bulk packing that can be incorporated into an ongoing packaging supply program.

Solution: Hanle Packing reviews the bag style, filling material, expected package capacity, and purchase quantity before recommending the HL-TAW standard configuration. The project uses the white PE valve with a 19.8mm inner diameter and carton-and-pallet packing for bulk handling.

Result: The converter receives a defined valve model for compatibility evaluation with its pouch structures and filling process. The final procurement decision can be made after technical confirmation, sample assessment where required, and agreement on production and packing requirements.

Frequently Asked Questions

What is the difference between HL-TAW and a coffee valve with a filter?

HL-TAW is supplied without a filter and is primarily intended for roasted coffee beans and other granulated products. A valve with a filter may be more appropriate when the packaging contains ground coffee, fine powder, or materials that could affect a filter-free valve configuration.

Can the HL-TAW coffee valve be used for ground coffee?

The suitability of HL-TAW for ground coffee should be confirmed according to the powder characteristics and packaging process. For powder-containing products, buyers should review whether a filtered valve design is required before selecting a model.

What pouch types are suitable for the 19.8mm coffee valve?

HL-TAW is suitable for laminated flexible packaging such as stand-up zipper pouches and bottom gusset bags. Actual compatibility depends on the pouch structure, available valve-placement area, and the packaging method used by the buyer.

What is the minimum order quantity for HL-TAW?

The standard MOQ for HL-TAW is 200,000 sets. Please provide the expected quantity and application details for a project-specific quotation review.

What information should be provided before requesting a quotation?

Please provide the filling product, bag type, target package capacity, expected order quantity, pouch material structure, and any requirements for valve color, size, filter configuration, or packing. These details help determine whether HL-TAW is suitable for the packaging project.
