Скачать или смотреть Manufacturing Process of Baby Diapers

Here's an overview of the complete manufacturing process of baby diapers:

Raw Materials:

1. Cellulose (wood pulp)
2. Polypropylene (backsheet, waistband)
3. Polyethylene (liner, wrapping)
4. SAP (Super Absorbent Polymer)
5. Adhesives (hot melt, pressure-sensitive)
6. Elastic materials (spandex, rubber)
7. Tapes (fastening, waistband)
8. Printing inks (for designs, logos)

Manufacturing Process:

Stage 1: Production of Individual Components

1. Backsheet production: Extrusion of polypropylene to create the backsheet material.
2. Liner production: Extrusion of polyethylene to create the liner material.
3. SAP production: Mixing of SAP with other materials to enhance absorbency.
4. Elastic ear production: Extrusion of elastic materials to create the waistband.
5. Tape production: Cutting and treating of tapes for fastening.

Stage 2: Absorbent Core Production

1. Mixing of cellulose, SAP, and adhesives.
2. Forming of the absorbent core using a machine (e.g., drum former).
3. Cutting and shaping of the core to desired size.

Stage 3: Diaper Assembly

1. Attachment of the liner to the backsheet.
2. Placement of the absorbent core.
3. Attachment of elastic ears (waistband).
4. Application of adhesives for secure bonding.
5. Attachment of tapes (fastening).

Stage 4: Converting and Finishing

1. Cutting and folding of diapers to desired size.
2. Packaging: Individual wrapping or bundling.
3. Quality control: Inspection for defects, absorbency testing.
4. Printing: Application of designs, logos, and product information.
5. Final packaging: Cartoning, palletizing.

Machinery Used:

1. Extruders (backsheet, liner)
2. Drum formers (absorbent core)
3. Cutting machines (core, diapers)
4. Adhesive applicators
5. Elastic ear machines
6. Tape applicators
7. Converting machines (folding, cutting)
8. Packaging machines (wrapping, cartoning)

Manufacturing Process Flow Chart:

1. Raw material sourcing
2. Component production
3. Absorbent core production
4. Diaper assembly

6. Quality control
7. Packaging and shipping

Key Manufacturers:

1. Procter & Gamble (Pampers)
2. Kimberly-Clark (Huggies)
3. Unicharm
4. SCA (Libero)
5. Ontex

Regulations and Standards:

1. FDA (US)
2. EU Directive 2007/47/EC
3. ISO 14001 (environmental management)
4. ISO 9001 (quality management)
5. ASTM (American Society for Testing and Materials)
