You can turn a clean, dry PET drink bottle into one continuous plastic strip by spirally feeding it past a guided blade. A small wooden jig with screws and a snap-off blade is one DIY option; a manual PET bottle cutter is another. The strip’s width and length vary with the bottle and cutter, and it is suitable for crafts or light utility—not safety-critical rope.
How the bottle becomes a continuous strand
The cutter holds a sharp blade at a fixed height. After you make a short starting cut near the bottle’s base, pull and rotate the bottle so its wall travels against the blade. The cut spirals around the bottle, unwinding its side wall as one long strip.
Use a PET beverage bottle that is clean and completely dry. Remove the label so it cannot snag, and check that the bottle is not badly crushed or torn. Bottle shape and cutter alignment affect how evenly the strip comes off; a particular width or length is not guaranteed.
Choose a cutter setup
| Option | What it involves | What to consider |
|---|---|---|
| DIY wooden jig | A small piece of scrap wood, four screws, a snap-off knife blade and a screwdriver. A saw and marker are listed for preparing and marking the wood in the DIY guide (DIY guide). | You set the blade position and guide height yourself. Secure the jig before use and check the alignment with a short test pull. |
| Manual PET bottle cutter | A ready-made hand-operated guide designed to cut PET bottles (product listing). | It avoids building the guide, but the cited material does not provide a controlled comparison of consistency, safety or performance against a homemade jig. |
| Hand-cut strips | A utility knife or box cutter, ruler or straight edge, and cutting mat (hand-cutting how-to). | This can make individual strips, but it does not guide a bottle through a spiral cut to produce a continuous strand. |
Make a strand with a guided blade
- Prepare the bottle. Wash it, let it dry, and remove the label. Work with the bottle empty.
- Secure the cutter. Set the jig or ready-made cutter on a stable surface and clamp or otherwise secure it so it cannot shift while you pull the bottle through.
- Set and check the blade. For a DIY jig, arrange the blade so it projects into the bottle wall at the height you want for the strip. Keep the cutting edge fixed and exposed only as needed for the cut. Test the alignment slowly before continuing.
- Open the bottom and start the strip. Use a knife to remove or open the bottle’s bottom, then make a short starter cut in the side wall. When making these initial cuts, direct the blade away from your body.
- Feed and rotate. Place the starter strip against the guide and pull the bottle steadily while rotating it. Keep the wall against the guide so the cut continues around the bottle rather than wandering across it.
- Stop if the strip tears or the cutter moves. Recheck the bottle, blade alignment and stability before trying again. Do not reach toward a moving or exposed blade to correct the cut.
In one homemade design described by Museo de Ciencias ZAMÁ, the strip was approximately 0.5 cm wide; that is an example from that particular setup, not a standard setting (Museo de Ciencias ZAMÁ project). Adjust the guide for the project and bottle rather than assuming every bottle will produce the same width.

Handle the blade carefully
These cutters use a sharp edge. Keep fingers out of the blade path, stabilize the tool before pulling, and make the first cuts away from your body. Children should have an adult handle all blade work. The how-to sources do not establish a formal risk assessment or protective-equipment standard, so treat this as careful knife work rather than a risk-free craft.
What can you use bottle string for?
Use it for crafts, tying, and other low-stakes, light utility projects. The cited how-to and product sources do not provide a verified breaking strength or load rating. Do not use homemade bottle strip as climbing rope, for lifting, or in any application where failure could injure someone or damage property.

A community recycling demonstration describes a separate, more involved rope-making process using additional equipment and notes machinery hazards; that is not the same as simply cutting a bottle into a strip (community demonstration).

There is no independently tested yield figure in the cited material. A 2020 vendor-style newsletter says a 0.5 litre bottle can produce “about 4-5 metres of strong cord”; treat that as a seller’s claim, not a measured guarantee (SECONDARY: WHAT’S NEW?). Museo de Ciencias ZAMÁ estimates 20 to 30 m for its project but says the length had not been measured, so it should not be treated as verified output (Museo de Ciencias ZAMÁ project). Bottle size, shape, cut width, and interruptions all affect the result.

Check recycling options before reusing a bottle
These instructions concern PET beverage bottles, but reuse is not automatically better for the environment than recycling. The U.S. EPA notes that accepted plastics can vary by location; check your local recycling provider’s rules before diverting a bottle for a project (U.S. EPA recycling guidance). The cited material does not establish that making bottle string has a lower environmental impact than local recycling.
