| Will it hold up in use? | Material tear and tensile information, flexing behaviour and the relevant sample checks. | Corners, strap attachments, openings and repeated folds. |
| Will the seams perform? | Seam construction, reinforcement, stitch setting and any agreed seam-strength checks. | Gussets, handles and areas with concentrated load. |
| How stable is the finish? | Finish adhesion, surface abrasion and colourfastness requirements relevant to the project. | Body panels, rubbing points, light linings and contact with clothing. |
| Is pineapple leather waterproof? | Evidence for the specific material’s water exposure performance, plus the complete bag construction. | Surface coating, seams, zipper openings and prolonged contact with water. |
| Does pineapple leather use plastic? | The complete composition, including binders, coating and backing. | Accurate material descriptions and any plastic-free specification. |
| Is pineapple leather biodegradable? | Evidence for the whole material, the conditions of a claim and the treatment of components in the finished bag. | Avoid describing a multi-component bag as biodegradable solely because one input is plant-derived. |
