Three layer polyester pouches are widely used for packaging food, pharmaceuticals, chemicals, and industrial products. They combine the strength of polyester with the barrier and sealing properties of other films. At Aman Polyplast, one of the trusted 3 Layer Polyester Pouches Manufacturers in India, every pouch goes through a carefully controlled process. Here is how it works.
1. Selecting the Raw Materials
Everything starts with film quality. A typical 3 layer structure includes:
- Outer layer (Polyester/PET): Provides strength, clarity, heat resistance, and a smooth surface for printing.
- Middle layer (Aluminium foil or metallised film): Blocks moisture, oxygen, light, and odour, extending shelf life.
- Inner layer (LDPE or CPP): Makes the pouch heat-sealable and safe for direct contact with the product.
Aman Polyplast selects food-grade or pharma-grade materials depending on the end use.
2. Printing
The polyester film is printed first, usually by rotogravure or flexographic printing. Brand names, product details, barcodes, and graphics are applied to the reverse side of the transparent film. This reverse printing protects the ink from scratches and from contact with the product. Colour matching and registration are checked closely so the print stays sharp and consistent.
3. Lamination
Lamination is the heart of the process. The printed polyester is bonded to the middle layer with a solvent-based or solvent-free adhesive, and the laminate is then bonded to the inner sealing layer. The material is cured afterwards so the adhesive reaches full strength. Proper curing prevents delamination and weak seals.
4. Slitting
The large laminated rolls are cut into narrower rolls that match the required pouch width. Precise slitting gives clean edges and uniform dimensions, which helps pouch-making machines run smoothly.
5. Pouch Making
The slit rolls are fed into pouch-making machines that fold, seal, and cut the film into finished pouches. Common styles include:
- Three side seal pouches
- Centre seal pouches
- Stand-up pouches
- Zipper pouches
- Pouches with tear notches or hang holes
Heat, pressure, and dwell time are controlled carefully to create strong, leak-proof seals.
6. Quality Testing
Quality checks run throughout production. They include seal strength, bond strength, thickness measurement, leak testing, drop tests, and barrier checks. Visual inspection confirms print accuracy and removes defective pieces.
7. Packing and Delivery
Finished pouches are counted, packed in cartons, and labelled. Careful packing keeps them clean and undamaged in transit to customers across Delhi, India, and overseas.
