1. Product Quality Issues

For cases where products are significantly inconsistent with confirmed orders, proofs, samples, material structures, or acceptance criteria, we initiate our after-sales verification process. Common issues include:

Obvious color deviations, severe registration errors, missing graphics, or abnormal blemishes in printing

Delamination, blistering, or other structural abnormalities in laminated materials

Significant dimensional discrepancies, poor sealing, abnormal opening, or inadequate heat seal strength in bags

Material structure inconsistent with confirmed order or samples

Upon verification that the issue is our responsibility, we will negotiate remedial actions with the client—including rework, replacement, refund, or other reasonable solutions—based on the issue proportion, impact on use, and delivery status.


2. Shipping & Delivery Anomalies

Obvious damage, moisture, compression, or product damage to outer cartons during transit

Quantity received inconsistent with shipping manifest or dispatch list

Logistics anomalies affecting client production or usage plans

We assist in verifying shipping records, packing lists, and receipt information, and coordinate with logistics providers as needed.


3. Technical Support for Actual Usage

For issues arising during the use of flexible packaging products on packaging equipment, heat sealing, or storage, we provide the following technical recommendations:

Recommendations for film feeding, tension, forming, and heat sealing parameters on automatic packaging machines

Heat sealing temperature, pressure, and time references based on material structure and thickness

Material optimization suggestions based on barrier, puncture resistance, low-temperature resistance, or oil resistance requirements

Troubleshooting for unstable film feeding, weak seals, air leakage, wrinkles, whitened seal edges, or bag damage
