Why bottles—and why RPET?

Bottles are made from PET (polyethylene terephthalate), a durable, recyclable plastic. When recycled, it becomes RPET—short for recycled polyethylene terephthalate. Choosing RPET reuses existing materials rather than extracting new fossil resources, supporting a circular economy and reducing environmental burden.

Bottle → Flake → Fibre → Fabric → Kind Bag

1) Collecting and sorting

The journey starts in recycling bins, community collection points, and municipal systems. Used bottles are gathered, then sorted by type and colour so that PET can be processed into high-quality RPET suitable for sustainable bag materials.

2) Cleaning and shredding

Bottles are thoroughly washed to remove labels, caps, and residues. They are dried and shredded into plastic flakes—the raw input for the next stage. Clean flakes are essential for strong, reliable fabric.

3) Melting and spinning into RPET yarn

The flakes are melted and re-extruded into fine fibres, then spun into yarn. This step transforms waste into a versatile textile input without the need for virgin polyester. Producing RPET can use significantly less energy and emit fewer CO₂ emissions than conventional polyester.

4) Weaving into fabric

RPET yarn is woven into a lightweight yet durable fabric designed for everyday life. It’s tear-resistant, water-resistant, soft, and foldable—ideal for a bag you can carry everywhere.

5) Cutting, sewing, and finishing

Skilled craftspeople cut and stitch the fabric into our signature designs. We work with ethical production partners who share our values of transparency and responsibility, ensuring that eco-friendly materials are matched by fair manufacturing.

When you choose Kind Bag, you’re supporting eco-friendly bag production that turns waste into value. Each reusable bag helps you replace hundreds of single-use carriers every year.

FAQ: your RPET questions, answered

What is RPET fabric?

RPET stands for recycled polyethylene terephthalate. It’s made by transforming post-consumer plastic bottles into yarn and fabric. If you’ve ever wondered what is RPET fabric or how it differs from polyester—the key is that RPET reuses existing plastics rather than creating new ones.

How does the recycled plastic bags process work?

In short: collect → clean → shred → melt → spin → weave → sew. This recycled plastic bags process reduces waste and can cut emissions compared to virgin polyester supply chains.

Is RPET durable and safe?

Yes. Our RPET fabrics are designed for strength and everyday wear. They’re tear-resistant and water-resistant—ideal for shopping, travel, and daily carry.

How does RPET compare to other sustainable bag materials?

Materials like organic cotton, jute, and hemp each have benefits. RPET’s advantage is that it uses existing plastic waste and performs similarly to polyester, making it a practical, long-lasting choice for reusable bags.

Beyond the bag: the bigger picture

Kind Bag has repurposed millions of bottles to date. By designing products that people love to use, we help reduce demand for single-use carriers and keep plastic circulating in the economy rather than in nature.

Every stage of our process is about transparency—from materials and certifications to design and durability. We’re committed to continual improvement and sharing our progress openly.
