bulk clear custom toiletry bags manufacturers

The manufacturing of transparent toiletry bags focuses on material safety, structural design, and detailed craftsmanship to ensure product practicality and durability.

I. Material Selection

PVC Material Certification

Rigid PVC materials that comply with the GB/T 8813-2008 standard are selected, with transparency meeting the optical performance requirements of GB/T 24157-2009. Phthalates are prohibited as plasticizers, and medical-grade DINCH bio-based plasticizers (with a migration rate only 1/10th that of conventional plastics) are recommended. Children's products must also pass the EN 71-3 heavy metals standard certification.

Functional Accessories

Hardware such as zippers and buckles must be treated with rust-proofing. If sponge/PEF (3mm-10mm thick) is used in the lining, it must pass the QB/T 2463 odor test.

II. Core Process

Waterproof Structure Optimization

Seams are coated with waterproof adhesive and then sealed with high-frequency heat-pressing. The edges are reinforced with TPU film lamination.

The zipper slot is sandwiched between the outer fabric and reinforced with double-topstitching.

Anti-fog and Anti-deformation Design

The interior can be pre-coated with an anti-fog coating, or users are advised to periodically use an oil-based cleaner to maintain transparency.

The factory packaging includes a built-in rigid support plate to prevent deformation during transportation.

III. Optimized Details

Visibility Design

The fully transparent bag features compartmentalized storage pockets (mesh or transparent) for quick location. The wet and dry compartments must be individually heat-sealed to prevent leakage.

Structural Adaptability

Cylindrical bags require a dedicated seaming machine to ensure smooth curved seams.

The handle base is reinforced with reverse ribs. The load-bearing test must be ≥ 5kg.

IV. Quality Inspection Requirements

Full Inspection Items

Zipper Smoothness (50 repeated openings and closings without sticking), Seam Tensile Strength (Seams withstand a 10N pull without unraveling), Water Splash Test (Water spray at a 45° angle for 1 minute, no penetration of the lining).

Labeling and Packaging

The outer box must be marked with a waterproof label, and the PE dust bag must be printed with a material certification code (e.g., FDA food contact grade).

Tips:

Poor-quality plasticizers can cause the package to become brittle or result in migration contamination.

Uncontrolled high-frequency hot pressing can cause perforation of the TPU film.
