bulk cosmetic pouch bags wholesale supplier

Fabric Cosmetic Bag Manufacturing Process:

I. Basic Structural Forming Process

Pattern Design and Cutting

Main fabric and interlining (fusible interlining) are laminated and cut. Common sizes are 27 x 38 cm or 34 x 46 cm rectangular substrates. 5-7 cm squares are cut off at each corner to create rounded corners.

Precision Control: Laser cutting molds ensure curves have an error of less than 0.5 mm to prevent sewing distortion.

Three-Dimensional Design

The side panels are creased and folded in half to form the skeleton. The connection to the main body is reinforced with transparent tape in both directions (cross-taping vertically and horizontally).

Capacity Expansion Technique: Pinched stitching creates a three-dimensional cavity in the flat fabric, increasing capacity by over 40%.

Zipper Integration System

Double layers of fabric hold the zipper teeth, and the interlining is stitched simultaneously to enhance strength. After installation, a single seam is sewn on both the front and back to prevent unraveling.

Explosion-Proof Design: Resin zipper pulls and fabric-wrapped ends withstand repeated opening and closing cycles exceeding 5,000.

II. Detailed Craftsmanship

A [Edge Treatment] --> B [Edge Strip Application]

A --> C [Reinforced Welt]

B --> D [4cm Wide Fabric Strip Four-Folded Edge]

B --> E [Fire-Sealed Edge to Prevent Burrs]

C --> F [Curved Edges to Prevent Wrinkles]

C --> G [Welt Sewn into the Contour for a Smooth Silhouette]

Functional Upgrades

Elastic Components: Elastic bands and buttons create an adjustable partition system to accommodate bottles of varying heights

Waterproofing: TPU film laminated to the lining, hydrostatic pressure ≥ 3000mm

III. Environmental Optimization

Material Recycling Technology

Using discarded insulation bags (PE aluminum foil) to cut 6cm wide substrates and splice them with hot-melt tape, reducing costs by 70%

Modular Design

22×25cm modules are magnetically connected with an 11.5cm overlap, allowing for flexible expansion of capacity

Transparent Window: 18×10cm PVC panels are embedded in a cardboard frame and secured with four-folded hemming strips.

IV. Surface Craftsmanship

Appliqué: Cut fabric scraps and apply them with the hidden needle method, using a stitch length of less than 2mm to ensure smooth edges.

Three-Dimensional Decoration: Small cotton-filled fabric pieces are created as "fat buttons" and sewn onto the cover for a tactile feel.

Gradient Dyeing: Water-based dyes are applied in layers, followed by a 60°C heat-fixing treatment for enhanced color fastness.

Note: All sewing steps must be aligned closely to the center mark of the fabric to avoid uneven stress and deformation.
