In the garment industry, the final stage of the production process is packaging. To support packaging operations, Dong Nam IK offers a range of products commonly referred to as packaging accessories and packaging materials.

​

A/ TAG FASTENERS / TAG PINS:

Labels attached to garments and other products require tag fasteners. Tag fasteners are made from polyester or nylon. The locking end of the tag pin is available in I-shaped, trapezoidal, or semicircular configurations.

The minimum fastener length is 7 mm; however, the most common lengths are 25 mm, 35 mm, 50 mm, 65 mm, 75 mm, etc., up to 9 inches. Dong Nam IK also supplies 25 mm trapezoidal-loop tag fasteners in roll form.

Loop tag fasteners are available in two configurations: round-loop and pointed-loop types.

Tag fasteners are mainly available in two colors: clear and black.

The tag fastener manufacturing process is as follows:

• Raw Material Preparation

  • PP, PE, or nylon resin, depending on the type of fastener.

  • Additives and colorants, as required.

• Filament Extrusion

  • The plastic resin is dried and fed into an extruder.

  • The resin is melted and passed through a die to form a continuous filament/cord.

• Cooling and Sizing

  • The extruded filament passes through a water bath or cooling system.

  • The filament is drawn at a controlled speed to achieve the required diameter and tensile strength.

• Winding

  • The filament is controlled for diameter, dimensional uniformity, and tension.

  • It is then wound onto bobbins or large reels.

• Conversion into Tag Fasteners

  • Large reels are divided into predetermined lengths.

  • The ends of the fasteners can be formed into T-shaped, arrow-shaped, or needle-shaped heads, depending on the type of tagging gun.

  • For fasteners with locking/connective ends, the ends are pressed or thermoformed using a heated mold.

• Quality Control

  • Diameter and length.

  • Tensile strength and breaking force.

  • Flexibility and stiffness.

  • Dimensions and geometry of the fastener ends.

  • Functional testing to ensure the fastener can be inserted through the tag and fabric without breaking or jamming.

• Packaging

  • Counting by reel or box.

  • Bagging, boxing, and labeling.

Plastic Bundle String & String Pin Manufacturing Process:

Plastic resin → Resin drying → Color/additive blending → Injection molding → Cooling → Ejection → Trimming/inspection → Packaging

1. Raw Material Preparation

   • The most commonly used material is Nylon 6/6 (PA66).

   • UV-resistant PA66, heat-resistant grades, or other engineering plastics may be used depending on the application requirements.

   • The resin must be properly dried because PA66 is highly hygroscopic.

2. Material Blending

   • PA66 resin is blended with color masterbatch and additives, where required.

   • For black cable ties intended for outdoor applications, an appropriate UV stabilizer/additive package is typically required.

3. Injection Molding

   • The plastic resin is fed into an injection molding machine.

   • The resin is heated, plasticized, and injected into the cable-tie mold.

   • Multi-cavity molds are commonly used to increase production efficiency.

   • The serrated strap and locking head are formed directly in the mold.

4. Cooling and Product Ejection

   • The mold is cooled to ensure dimensional stability.

   • Once the mold opens, the ejection system pushes the cable ties out of the mold.

5. Post-Molding Processing

   • Sprues/runners are separated from the finished products where required by the mold design.

   • Defective products are removed, including parts with short shots, flash, deformation, or incompletely formed teeth.

6. Quality Control

   Key inspection criteria include:

   • Strap length and width.

   • Locking-head dimensions.

   • Tooth dimensions and accuracy.

   • Tensile/breaking strength.

   • One-way locking performance.

   • Heat and UV resistance for specialized grades.

   • Appearance and color consistency.

7. Packaging

   • Automatic or manual counting.

   • Packing according to specified quantities, such as 100, 200, or 500 pieces per bag.

   • Printing the product code, dimensions, color, and production batch information.

​

C/ DESICCANT PACKETS:

Desiccant packets are commonly used in footwear, jackets, leather goods, wooden products, and other products to minimize moisture and mold growth during transportation.

​

Dong Nam IK supplies only round silica gel beads with intact, non-crushed particles. As a result, the desiccant provides high moisture adsorption capacity over an extended period.

​

We primarily use two types of packaging materials for the sachets: paper and nonwoven fabric.

​

Because the desiccant beads must be protected from exposure to the surrounding environment, we manufacture the packets only upon receipt of an order, with the filling weight customized according to the customer's requirements.

​

Silica Gel Desiccant Packet Manufacturing Process:

Raw material → Drying/activation → Screening → Weighing/dosing → Sachet forming/filling → Sealing → Inspection → Packaging

1. Desiccant Preparation

   • Granular silica gel.

   • White silica gel, blue indicating silica gel, or orange indicating silica gel may be used depending on requirements.

   • Particle size and moisture adsorption capacity are inspected.

2. Drying and Activation

   • Silica gel is heated to remove the moisture previously adsorbed.

   • After reaching the specified moisture level, the material is cooled under controlled conditions to minimize re-absorption of moisture.

3. Screening and Classification

   • The silica gel is screened according to particle size.

   • Dust, broken particles, and foreign matter are removed.

4. Weighing and Dosing

   • An automatic weighing system doses the required quantity of silica gel according to the sachet weight, such as 1 g, 2 g, 5 g, or 10 g.

   • Filling-weight tolerance must be carefully controlled.

5. Sachet Material Preparation

   • The packaging material is typically specialized porous paper, nonwoven fabric, Tyvek, or another suitable permeable material.

   • The sachet material must allow water vapor to pass through while retaining the desiccant particles inside.

6. Sachet Filling and Sealing

   • Sachet forming → silica gel dosing → filling → heat sealing.

   • Warning statements such as “DO NOT EAT”, together with product information, may be printed on the sachet.

7. Quality Control

   • Individual sachet weight.

   • Seal integrity.

   • Dimensions.

   • Mechanical strength.

   • Moisture adsorption capacity.

   • Initial moisture content of the silica gel.

   • Appearance and print quality.

8. Cartoning

   • Automatic counting.

   • Packing into bags or cartons according to the specified quantity.

   • Finished products are stored in a dry, sealed environment to prevent the silica gel from absorbing moisture before use.

​

D/ MOISTURE-ABSORBENT TISSUE PAPER:

Tissue paper is used as an inner liner inside products to enhance moisture absorption and help keep products dry.

​

Dong Nam IK provides custom cutting services according to customer-specified dimensions.

Our tissue liners provide effective moisture-control performance, particularly for leather footwear, metal products, and heavy garments.

​

For garments packaged using a hanging-pack method, Dong Nam IK also supplies various types of garment hangers and hanger covers, as well as garment covers made from foam, nonwoven fabric, or insulating sheet materials.

Dong Nam IK offers a wide range of packaging accessories to meet different customer requirements.

Moisture-Absorbent Tissue Paper Manufacturing Process:

Pulp/fiber → Slurry preparation → Additive blending → Papermaking → Pressing → Drying → Calendering/finishing → Winding → Inspection → Cutting

1. Raw Material Preparation

   • Suitable cellulose pulp/paper fibers.

   • Different fiber types may be blended to adjust strength and air permeability.

   • A key requirement is that the paper must allow water vapor transmission while preventing desiccant particles from passing through.

2. Pulp Refining and Blending

   • The pulp is dispersed in water.

   • The degree of refining is adjusted to control strength, porosity, and permeability.

   • Sizing agents, strength additives, or other application-specific additives may be incorporated as required.

3. Papermaking

   • The pulp slurry is delivered onto the forming wire.

   • Water drains through the wire while the cellulose fibers form a wet paper web.

4. Pressing

   • The wet paper web passes through a press section to remove excess water.

   • Press pressure is controlled to achieve the desired thickness and porosity.

5. Drying

   • The paper is dried using drying cylinders or a hot-air drying system.

   • This is a critical stage for controlling final moisture content and preventing dimensional distortion.

6. Surface Finishing

   • Light calendering may be applied to control thickness, smoothness, and strength.

   • Surface treatment should not excessively reduce water-vapor permeability when the paper is intended for use in desiccant sachets.

7. Winding and Slitting

   • The finished paper is wound into jumbo rolls.

   • The rolls are subsequently unwound and slit/cut to the dimensions required for desiccant sachet packaging equipment.

8. Quality Control

   Key quality parameters include:

   • Basis weight (g/m²).

   • Thickness.

   • Tensile strength.

   • Tear/burst strength.

   • Porosity and water-vapor transmission.

   • Desiccant particle retention and resistance to dust/particle leakage.

   • Paper moisture content.

   • Cleanliness and appearance.

​

Key Performance Consideration:

The most important consideration is to achieve the right balance between water-vapor permeability and particle retention. If the paper is too impermeable, the silica gel will absorb moisture too slowly; if it is too porous, silica gel dust or particles may escape through the paper.
