Beiyin Packaging has published an eight-input pre-sample brief to help coffee roasters, brands and packers define project requirements before requesting custom coffee-bag samples.
CHAOYANG, China, July 31, 2026 — Beiyin Packaging, the brand of Kazuo Beiyin Paper and Plastic Packing Co., Ltd., has published a practical pre-sample brief for coffee roasters, brands and packers preparing a custom coffee-bag project.
The resource is organized around eight inputs that should be defined before a sample is requested: the coffee and its condition at filling; the expected commercial quantity and exact purpose of the sample; the finished pouch format and dimensions; valve, opening and reclosure requirements; filling and sealing equipment; storage and distribution conditions; artwork control; and trial acceptance criteria.
The brief separates three sample types that answer different questions. A blank size sample can help a team review dimensions and handling. A printed proof can support artwork, layout and visual checks. A production-material trial is intended for project-specific testing with the actual coffee, process and finished package.
As the published guide states, “A blank size sample, a printed proof and a production-material trial are not interchangeable.” Naming the exact decision first helps prevent a visual mock-up from being treated as evidence of production performance.
The guide also states that a generic film description or unfilled sample should not be treated as proof of compatibility, barrier performance, seal integrity, shelf life or suitability for a destination market. Those questions require validation against the actual coffee, equipment, distribution route and applicable requirements.
The public worksheet gives project teams a concise structure for an initial request for quotation or sampling discussion. It links the sample objective to practical choices such as flat-bottom, stand-up and side-gusseted formats; one-way degassing valves where required by the project; zipper or other reclosure features; and the filling and sealing method.
