As a trash can factory, when a customer asks us to handle an order for custom liner sizes, we manage it as a controlled project rather than a catalog request. The process starts with a detailed intake: bin dimensions, shape, rim style, usage environment, preferred material, thickness, gusset, seal type, perforation, core, packaging, order volume, and destination market requirements. Our engineering team reviews the specification against existing cutting programs, molds, and film formulations. If an existing platform can be adapted, we confirm the revised dimensions on a drawing; if new tooling or cutting files are required, we quote the setup cost and lead time before proceeding.

We then produce pre-production samples in the agreed material and thickness. These samples go through liner fit testing on the actual trash can or a verified replica, checking length, width, lip fit, tear resistance, load performance, and dispensing. We share fit feedback and measurement reports with the customer, adjust the sample if needed, and lock the approved specification sheet. Bulk production is scheduled only after written approval.

During production, our QC team checks film thickness, width, seal strength, perforation, and roll or carton count at defined checkpoints. Finished custom trash can liners are packed according to the approved label, core, and carton requirements, then prepared for shipment with the relevant documentation. We keep the approved specification and sample record on file so repeat orders for the same custom liner sizes can be processed quickly and consistently. This workflow supports reliable OEM liner production, reduces fit errors, and helps customers control costs.
