18.9mm Coffee Bags Valve with Filter for Pouches | HL-TA

18.9mm Coffee Bags Valve with Filter for Powder Pouch Packaging

HL-TA is a coffee bags valve with filter designed for flexible packaging containing coffee powder and other powder-based products. Its 18.9mm inner diameter, 5.1mm height, and integrated filter structure provide a defined valve option for laminated pouches where fine particles need to be considered during product filling and storage.

The one-way valve structure allows gas released inside the pouch to move outward while helping limit reverse airflow into the package. The filter layer provides an additional barrier against powder or particulate material reaching the valve path, making HL-TA suitable for coffee powder, flour powder, baking powder, and similar packaging applications.

Why a Filtered Coffee Bags Valve Matters for Powder Products

Powder-based products can create a different packaging challenge from whole coffee beans. Fine particles may move inside the pouch during filling, sealing, transport, or handling. A filter-free valve may not be appropriate for every powder packaging project, particularly when material particles could affect the valve area.

The HL-TA coffee bags valve includes a filter layer to help reduce powder and particulate entry into the valve structure. Buyers should still evaluate the product characteristics, filling process, pouch format, and valve installation position before selecting a filtered valve model.

• Supports controlled gas release from sealed flexible packaging
• Includes a filter layer for powder-containing packaging applications
• Helps reduce the risk of particles reaching the valve path
• Helps manage internal pressure in coffee and powder packaging pouches
• Provides an 18.9mm valve format for defined pouch-panel layouts

How the HL-TA One-Way Coffee Valve Works

The HL-TA coffee bag air vent is integrated into laminated flexible packaging. When gas builds up inside the sealed pouch, internal pressure allows gas to move outward through the valve structure. This helps reduce the pressure that may otherwise cause pouch expansion or deformation.

After the internal pressure decreases, the one-way valve configuration helps limit outside air from moving back into the package. The integrated filter layer is designed to help reduce contact between the valve path and powder particles inside the pouch.

With Filter vs. Filter-Free Valve

The right valve configuration depends on the product being packed. A filtered coffee bags valve is generally considered when the packaging contains fine powder or particles, while a filter-free valve may be suitable for whole coffee beans and other larger granulated materials.

Product Specifications

What to Confirm Before Selecting HL-TA

HL-TA is designed for powder-containing flexible packaging, but valve selection should be based on the actual filling material and pouch design. Buyers should confirm whether the powder characteristics, package capacity, and available pouch-panel area are suitable for an 18.9mm filtered valve.

• Confirm whether the product contains coffee powder, flour powder, baking powder, or another fine-particle material
• Confirm the pouch format, available valve placement area, and required package capacity
• Provide the laminated pouch material structure and sealing process for project review
• Confirm whether a filter layer is required according to the product particle size and filling condition
• Provide the expected order quantity and packing requirement before quotation

OEM and ODM Options

Hanle Packing can review OEM and ODM requirements for filtered coffee bags valve projects according to the filling material, pouch structure, target quantity, and technical specifications. HL-TA is supplied as a standard white PE valve with an 18.9mm inner diameter and integrated filter, while project-specific requirements can be evaluated before production planning.

• Size Review: Valve dimensions can be reviewed against the pouch structure and available installation area
• Color Options: Color requirements can be assessed according to project specifications and order quantity
• Filter Configuration: Filter requirements can be reviewed according to the filling material and powder characteristics
• Sample Assessment: Sample arrangements can be discussed for pouch matching and application evaluation
• Bulk Packing: Inner bag, carton, pallet, and export-packing requirements can be confirmed before shipment

Choosing Between HL-TA and HL-TB Coffee Valves

HL-TA and HL-TB are one-way degassing valves for flexible packaging, but they are intended for different filling materials. HL-TA includes a filter and is positioned for powder-containing products, while HL-TB is a filter-free model intended primarily for roasted coffee beans and other granulated contents.

HL-TA may be considered when the packaged product contains coffee powder, flour powder, baking powder, or other fine particles that require a filtered valve configuration. For roasted coffee bean packaging and other granulated materials, review the HL-TB coffee bag one way valve. Final selection should be confirmed according to the filling product, pouch structure, valve placement area, and packaging process.

Standard Configuration and Project Requirements

HL-TA is supplied as a standard white PE coffee bags valve with an 18.9mm inner diameter and an integrated filter layer. This configuration is intended for flexible packaging projects involving coffee powder and other powder-based products where particle management is an important selection factor.

For projects involving different valve dimensions, color requirements, filter arrangements, pouch formats, or application conditions, Hanle Packing can review the technical requirement before quotation. Product suitability should be confirmed according to the packaging material, filling product, expected quantity, and requested specifications.

Applications for Coffee Powder and Fine Particle Packaging

HL-TA is primarily intended for laminated pouches containing coffee powder and other powder-based products. Its filtered valve structure can also be reviewed for packaging projects that need controlled gas release while considering the movement of fine particles inside the pouch.

• Ground coffee and coffee powder packaging
• Flour powder packaging
• Baking powder and dry baking ingredient packaging
• Stand-up pouches with zipper closures
• Bottom gusset bags for powder packaging projects

Typical Procurement Scenario

A flexible packaging buyer is developing stand-up coffee pouches for ground coffee products. The project requires a one-way valve that can release gas from the sealed bag while taking into account the fine particles generated during filling and transport.

Buyer Requirement: The buyer needs a white PE coffee bags valve with an integrated filter, an 18.9mm format suitable for the selected pouch panel, and bulk packing for high-volume procurement.

Solution: Hanle Packing reviews the filling material, pouch structure, valve placement area, expected package capacity, and purchase quantity before recommending the HL-TA standard configuration. The model is supplied with an integrated filter layer and packed in inner poly bags, outer cartons, and pallets.

Result: The buyer receives a defined filtered-valve specification for compatibility evaluation with the selected coffee powder pouch and filling process. Final procurement can proceed after confirming product suitability, sample requirements where applicable, and production scheduling.

Frequently Asked Questions

What is the main difference between HL-TA and a filter-free coffee valve?

HL-TA includes a filter layer and is positioned for coffee powder and other powder-based products. A filter-free valve may be more suitable for whole coffee beans or larger granulated materials, depending on the pouch structure and packaging process.

Can HL-TA be used for roasted coffee beans?
