Update:30 Jul 2020

What can a mineral water bottle cap do and what kind of plastic is it made of?

Wonderful use of mineral water bottle cap
1. Do water sprinkling
We can keep the mineral water bottle. We can use sharp objects to prick some freezing on the top of the bottle, or prick a few small holes with a needle, and then fill the bottle with water, cover it, and then we can water it.
2. Make a pet straw rack
For example, a large mineral water bottle can have a hole in the top half, then iron the edge with a lighter, and fix it on the cage with iron wire in the middle, which can be used as a pet straw rack.
3. Making plastic flowers
You can use a mineral water bottle to cut some round ones and use a fire machine to make plastic flowers.
4. It can be potted
Plastic bottle big can open a big hole, fill it with soil to grow vegetables, flowers and meat.
5. Make storage box for small accessories
You can cut down the bottom of the two plastic bottles, install the zipper and glue it up to make a plastic storage box. Oh, it is specially used to hold some small parts.

You can cut off the bottom of the mineral water bottle, reduce it from large to small, and then fix it in the middle with a piece of iron wire. You can make a jewelry box. If you have time, you can do some pieces to stick it up. It will be more beautiful.

Plastic analysis of mineral water bottle cover
1. High pressure polyethylene LDPE
It has low crystallinity, molecular weight of 50000-500000, low softening point of Vicat, good flexibility and good low-temperature resistance. The products can be used at low temperature from - 40 ℃ to - 60 ℃ without cracking; it has good electrical insulation, low water absorption and good corrosion resistance; it can be used for injection molding, extrusion, foaming process, thermoforming, hot air welding, hot welding, coating, etc.
It has good rigidity, high endurance, good strength and good air permeability. It is suitable for cooking bags, film lined bags and extruded pipes.
3. Low pressure polyethylene HDPE
High density, high crystallinity, good temperature and oil resistance, good electrical insulation and impact resistance, aging resistance is better than PP plastic, working temperature is better than PVC and LDPE.
4. It is a kind of environment-friendly odorless plastic with good corrosion resistance. It meets the requirements of RoHS, reach, PAHs and some food grade environmental protection.
