Custom PE Bags and Film Manufacturing Process

From Approved Specification to Batch Inspection and Export Release
Step 01

Material & Specification Review

The project begins with the packed product, finished dimensions, unit weight, quantity, intended use, destination market and required documents. The approved specification records the resin, additives, colorants, single-layer thickness, tolerances, closure or seal construction, printing and packing method before production.

Step 02

Film Extrusion & Gauge Control

LDPE, LLDPE, HDPE or a project-specific PE blend is extruded according to the approved film structure. Production checks cover the applicable resin identification, film width, single-layer gauge, thickness distribution, appearance and winding. The order specification records the tolerance, measurement locations, sampling frequency and acceptance criteria.

Step 03

Printing & Artwork Control

Artwork is checked for dimensions, color references, coverage, registration, warning text and barcode areas. The printing method is selected according to the film, design and order quantity. The approved digital proof, physical sample where applicable, viewing conditions and permitted variation become production references together with the written specification.

Step 04

Bag Converting & Inspection

Film is converted into the required flat, ziplock, slider zipper, self-adhesive or other bag structure. In-process and final checks cover the applicable finished dimensions, single-layer thickness, seals, zipper or adhesive construction, opening performance, appearance, printing and packing. Inspectors use the test method, sample size and acceptance criteria recorded for the order.

Step 05

Packing & Export Release

Finished products are packed in the specified inner bags, cartons, pallets or moisture-protected export configuration. Before release, the team checks the applicable quantity, labels, packing marks, inspection records and shipping documents. Approved specifications and order records support traceability and repeat-order consistency, while the shipment plan states the freight method, Incoterm and destination requirements.

Start With Your Packaging Specification

Most custom orders require approximately 20–30 days for production after the specification, artwork, sample requirements and commercial terms are approved.
