Transparent Cosmetic Bag Production Process:

I. Basic Material Preparation

PVC Film Selection

Use a PVC film with a thickness of 0.8-1.2mm. It must be low-temperature burst-resistant (no cracking at -20°C). Common sizes are 18 x 28cm (medium-sized bag) or 20 x 30cm (large-capacity bag). Mass production uses anti-fog coated PVC to prevent moisture from affecting visibility.

Supplementary Materials

Edge: 4cm wide cotton strips folded in four, ironed to shape.

Zipper: Waterproof resin zipper preferred (20-25cm length).

Adhesive: Industrial glue for high-frequency welding or hot-melt adhesive with a hair straightener.

II. Production Process

Mass Production Process

High-frequency Welding: 13.56MHz high-frequency welding machine welds seams in 0.5 seconds, eliminating the risk of pinhole seepage.

Three-Dimensional Molding: 200°C mold hot pressing for 10 seconds to achieve a rounded bottom/multi-compartment design.

Printing: Utilizing flexible printing technology, the side panel pattern is reproduced with >95% accuracy.

III. Strengthening Process

Waterproof Sealing Seams coated with polyurethane waterproof adhesive, hydrostatic pressure tested to ≥ 5000mm

Reinforced Structure

Hot-pressed triangular support structure on the bottom increases load-bearing capacity (up to 5kg)

D-shaped buckle connects to the webbing handle

Optimized Visibility

The transparent window is made of a double-layer PVC composite, scratch-resistant and transparent.

The latest technology allows for embedded LED light strips to achieve a luminous effect (with added fluorescent agent)

IV. Design Trends

Split Structure: Separate wet and dry compartments (bathroom area + makeup area)

Foldable Design: TPU material splicing allows for compact storage

Customization: UV printing technology supports batch pattern customization

PVC film thickness and transparency for transparent cosmetic bags:

1. Thickness Selection Criteria

Everyday Standard (Lightweight)

Preferred Thickness: 0.15-0.30mm

Features: Soft and foldable, weighing only 80-120g

Suitable for: Accommodates up to 5 small items such as lipstick and compact powder

Travel Storage (Compression-Resistant)

Recommended Thickness: 0.50-0.80mm

Features: Hot-pressed triangular support structure at the bottom, supports up to 3-5kg

Suitable for: Transporting glass bottles such as lotions and toners

High-End Display Style (Customizable)

High-End Style Optional Thickened Film: 1.0-1.2mm

Features: 40% increased clarity for 3D texture engraving, compatible with embedded LED light strips

2. Transparency Core Parameters

Transmittance Grading

Economical: Transmittance 60% (haze > 15%), creating a hazy, frosted finish

Recommended: Transmittance ≥ 90% (haze < 5%), achieving glass-like clarity

90% transmittance film improves visibility three times in low light compared to 60% film.

Anti-Fog Technology Options

Ordinary PVC: Transmittance decreases to 50% after condensation

Anti-Fog Coated: Maintains 85%+ transmittance (suitable for high-humidity environments like bathrooms)

3. Innovative Materials

TPU: Transparency comparable to PVC, with improved low-temperature resistance (no cracking at -20°C)

Bio-based PVC: Transmittance 88%+, with a degradation cycle shortened to 50 years

Acrylic Composite Film: 95% transmittance at 2mm thickness, but limited flexibility
