Find the right material for your packaging.

Choose around the packed product, weight, handling route and required appearance. Film thickness should be reviewed alongside material structure, opacity, seams and closure performance; a thicker film alone does not guarantee the right pack. State the thickness unit and whether you are referring to a single film wall.

Where no specification exists, share an existing bag or describe the performance you need. Compare proposed samples using the actual contents and agree the material, dimensions and acceptance criteria before placing the bulk order.

Include the requested recycled-content proportion and the evidence required by your purchasing team. Ask how the claim is defined and which documentation supports the proposed material. Colour, appearance and performance should be reviewed on a representative sample.

Recycled content and recyclability describe different things. Do not add disposal wording or environmental claims based only on a bag colour or appearance; confirm the material information and the collection guidance relevant to the destination before finalising printed messaging.

A flexible outer mailer provides no rigid structure by itself. Fragile products, sharp edges or concentrated loads may need a suitable inner box, cushioning or a different packaging format. Review the whole packed item and its handling route before deciding on a bag.

For heavier contents, specify the packed weight and discuss the film, seams and closure together. Evaluate a representative packed sample and agree any necessary handling or transit assessment rather than choosing only by bag dimensions or thickness.

A stock sample helps you assess an existing format or material. A digital proof checks artwork positioning and layout, but does not demonstrate physical bag strength, colour on the actual film or packed fit. A custom physical sample or pre-production sample can address the agreed construction and print requirements.

State what you want to approve and which features must match production. Confirm sample availability, cost, quantity, timing and shipping separately, and keep the approved sample or proof linked to the final specification.

Start with the product you are packing, the usable bag width and length, closure flap, quantity per size and delivery destination. Add the material or thickness if known, plus print colours, artwork and any packing requirements. A photo of the packed item or an existing sample can help explain the application.

If the specification is still open, describe the product weight, dimensions and dispatch process. The quotation should identify the agreed specification, sample scope, setup charges and shipping basis so different options can be compared fairly.

Define the characteristics that matter for your application: usable dimensions, film thickness, opacity, seam consistency, closure behaviour, print appearance and quantity. Link these to an approved specification or sample, with agreed measurement methods and tolerances where relevant.

If your purchasing team needs inspection records, third-party checks or supporting documents, request them before ordering. Confirm the scope and acceptance criteria for that order; do not assume a certificate, test result or inspection service is included without confirmation.
