Quality Inspection

Quality Control & Inspection for Custom Packaging

From Material Inspection to Final Shipment, Every Custom Packaging Order Is Checked for Consistency, Function and Appearance.

Quality is the best standard to influence our progress and measure our creativity; The quality of various products and services is directly related to customer satisfaction, so quality can be considered the core of our enterprise competitiveness!

The pursuit of quality can improve our productivity, save input costs, reduce inventory backlog, improve the market position of the enterprise, and obtain the recognition and praise of the majority of users.

Our qualifications and certifications

FSC® CoC Chain of Custody Certification

Every sheet of paperboard and every paper raw material we use comes from sustainably managed forests or legal recycled sources. FSC is the green packaging passport for European and American brands and international buyers — Amazon’s Climate Pledge Friendly, IKEA, Starbucks, and many others require their packaging suppliers to hold FSC certification. Choosing FSC-certified packaging can also bring about 5%-15% green premium to your end products.

ISO 9001:2015 Quality Management System Certification

We have established a standardized operating system (SOP) and complete production traceability covering the entire process: raw material incoming → production → finished goods outgoing. ISO 9001 means stable product quality and predictable delivery, effectively eliminating purchasing trust risks in international trade, so you can cooperate with confidence without repeated factory inspections.

Professional testing equipment

Grammage Tester – The Foundation of Paper Quality

Grammage (basis weight) of paperboard is a fundamental indicator affecting the stiffness, thickness and compression strength of paper boxes. We use a grammage tester to accurately measure each batch of raw materials, ensuring that the paperboard weight meets order requirements and avoiding softness, deformation or insufficient compression resistance caused by insufficient grammage.

Bursting Strength Tester – Guardian of Transport Burst Resistance

This tests the ability of corrugated paperboard to resist rupture when subjected to external extrusion or impact. This indicator determines whether cartons can withstand rough handling and violent sorting during long-distance cross-border logistics. Insufficient bursting strength may cause cartons to burst during transit, damaging the inner products.

Color Density Tester – Expert in Color Accuracy for Custom Printing

Color accuracy is at the core of custom printing. We use a color density tester (reflection densitometer) to quantitatively measure ink density on printed matters, ensuring that density values for cyan (C), magenta (M), yellow (Y), black (K) and spot colors (e.g., Pantone) remain stable within the standard range. By comparing density deviations between standard proofs and production samples, we effectively control batch-tobatch color differences and guarantee high consistency of your brand colors.

Pre-shipment Inspection Process

Step-by-Step Check from Outer Carton to Product

Before each batch of finished paper boxes leaves the factory, our quality inspectors verify the following key points one by one:

Outer carton labeling & quantity

Verify marks, model number, warning signs and packing quantity, ensuring consistency with customer requirements.

Product comparison against sample

Compare finished products with the customerapproved sample (printing, foil stamping, diecut pattern, text content) to eliminate graphic or text errors.

Critical dimension measurement

Use a steel ruler or caliper to measure length, width, height, window position, crease line positioning, etc., with tolerance controlled within ±0.5mm.

Function test

Manually test opening/closing smoothness, magnetic force, liner fit, snaplock firmness to ensure user experience.

Cleanliness check

Visually confirm no glue residue, dust, oil stain, fingerprints, etc. on the surface.

Packaging safety confirmation

Check foam paper wrapping integrity, inner/outer carton sealing quality, and strap tension.

AQL Sampling Standard

Internationally Recognized Quality Assurance Commitment

We strictly follow AQL 2.5 / 4.0 for pre-shipment random sampling inspection:

Critical defects

Cannot be formed, severely damaged, wrong print content → AQL 0% (zero tolerance, whole batch rejected)

Major defects

Burst line (cracking at fold), obvious color difference, outoftolerance dimensions causing inability to fit inner product → AQL 2.5

Minor defects

Tiny scratches, slight print misalignment, very few dust spots → AQL 4.0

Inspection results for each sampled piece are recorded in a detailed inspection log, making defects traceable to the specific sample.

Packaging Safety

ThreeLayer Protection, WorryFree Ocean Shipping (Foam Paper + Double Carton)

We use a threelayer progressive protective packaging system to ensure products remain intact during longdistance sea freight and courier transportation:

Layer 1 (product-level cushioning)

Each finished paper box is wrapped with foam paper to absorb vibration and prevent scratches.

Layer 2 (inner carton fixation)

Wrapped products are neatly placed into an inner carton that closely fits, minimizing internal movement.

Layer 3 (outer carton compression resistance)

The sealed inner carton is then placed into a highstrength exportgrade outer carton that resists compression and puncture.

Before shipment, we confirm one by one: foam paper coverage is complete, inner carton sealing is secure, and outer carton strap tension is appropriate.
