SHRINKABLE BUNDLES OF PLASTIC BOTTLES

Send

I had an idea how to make heat-shrinkable clamps that could be used for various household purposes. The idea is based on the ability of PET plastic to compress when exposed to hot air. Empirically, I came up with three types of clamps, which I’ll talk about.
This clamp is in two parts.

Compound clamp

Production of the first part:
The first element of the ligament is a ring about 2 cm wide cut from a plastic bottle. The diameter of the ring is determined by the diameter of the bottle: the larger the volume of the bottle used, the larger the working diameter of the finished clamp.

Holes are made at the edges of the strip using a punch. To make it more convenient to do, I fold and iron the ring to get a double strip of plastic. I also punch a second hole, combined with the first, to expand the holes.
Production of the second element:
For the second part of the bunch, I suggest using a plastic handle removed from wine packs. It has T-shaped ends that are seamlessly connected to the handle itself, therefore it is sufficiently reliable to break.

Use of a collar

One side of the plastic handle (T-shaped end) is passed through the hole in the ring of the bottle. Next, the clamp is encircled around the crimped product or connected items and fastens at the second end.

In order for the harness to tightly compress and fix the desired object, it is necessary to apply a thermal effect. For these purposes, you can use a building hair dryer (heat gun) or other sources of hot air. At home, even a gas burner for a household stove is suitable.
When exposed to heat, the strip cut from a plastic bottle shrinks, resulting in a reliable fixation of two elements.
Note! The shrinkage of the plastic was not very large, so it is necessary that the strapping initially fit as tightly as possible to the object.
For this type of clamp, I use pens from plastic buckets for mayonnaise. The general technology for making harnesses is similar to the previous version, with one difference: such handles have round snap loops, so round holes are made in PET plastic strips.
Handles from plastic buckets are longer, therefore they allow crimping larger diameter items.

In the end, I will tell you how I made a cut-out clamp from PET plastic.
For this strapping, I cut several strips about 1 cm wide from a plastic bottle. I made a hole at one end with a punch.
On the other end, I made semicircular cutouts located symmetrically on both sides of the strip.
After this, it remains only to skip the sharp end of the strip into the hole and the shrink sleeve is ready!

Advice! If you want to extend the plastic strapping, then you can combine several strips in one design. As practice has shown, the rigidity of the connection remains as reliable.
