Whole-Bean and Ground Coffee: Approve a Shared Bag Specification

Using one bag size or construction can simplify a purchasing program, but the project still contains two products. Record which elements the brand hopes to keep common: dimensions, film, zipper, valve, print route or artwork family. Mark which elements may differ if the filled-product review requires it.

Do not treat the same labeled net weight as proof of the same fit. Check each actual coffee’s fill level, headspace, access to the final seal and finished presentation. The size and headspace guide provides the broader sizing context; this article focuses on approving one specification across two contents.

Valve manufacturer PLITEK describes one-way degassing systems and lists filtered options for ground coffee. This supports asking about the exact valve and product form; it does not establish that P&M uses a PLITEK component or that one model suits every coffee.

For the proposed package, record the valve reference, any filter, installation position and the supplier’s relevant documentation. With ground coffee, include the product’s powder behavior and the question of powder reaching or obstructing the valve. Identify the installed configuration rather than accepting “coffee valve” as a complete specification.

Record roast and grind references, the actual packing interval, filling and sealing equipment, and any gas-flushing process. Keep timing and acceptance criteria specific to the project. A universal waiting period or shelf-life promise would hide the conditions that the paired trial needs to address.

This original matrix helps a roaster, buyer and supplier distinguish shared parts from separate product observations. It is not a standardized test protocol.

A whole-bean sample may be accepted while the ground-coffee sample still needs a filter question answered or a different fill check. Preserve that distinction. Do not combine both into “bag approved” merely to simplify the purchase order.

If the proposed solution changes the valve or bag geometry, identify which earlier observations remain relevant and which need repeating. Use the valve substitution guide when an alternate component is proposed, and the valve evidence guide when reviewing inspection records.

Keep package observations and coffee-quality approval connected but distinct. A valve-related measurement does not by itself establish the coffee’s accepted taste or shelf life. The responsible product team should identify the conditions and evidence supporting its quality decision.

For a custom coffee-bag review, send both product descriptions, bag references, desired shared components, quantity per SKU and sample objectives. State whether the request concerns an empty sample, an appearance proof or a production-representative filled trial so that its limits are clear.

Retain the accepted specification with the two product approvals and any exceptions. Confirm production and delivery timing against that approved scope. If the result requires separate configurations, make the difference visible in the order rather than letting a shared artwork family conceal it.
