Polypropylene Strapping is the most commonly used and least expensive
of all strapping materials, which can be manufactured from origin plastic materials or from recycled plastic materials
It's light and easy to apply and recycle.
Poly strapping is available in both hand grade and machine grade and can be sealed with buckles,
seals, heat seals, or with a friction weld strapping tool.
If you want to have a heavy duty strappinng you have to use the poly-strapping clip-with hand grade tool to close it

If you have a machine which can produce as fast as 90 pieces/minute for your production, that means you can produce about 40,000 to 50,000 pieces in one working day which is about 148 KG or 185 KG per day( if the size is 16x31x0.5mm galvanized steel) and if you can sell the products at a price of 0.005 USD/piece in your local market as minimum pricing, you will get a 200-250 USD output and sale per day and will get 36,000--45,000 USD output and sale in 6 months, and you will get the machine investment funds back after six months' production and sales if you have a 15% minimum profit out of production and sales at your local market ( but of course depending on sale's ability) on the condition that you get galvanized steel coil at a price of less than 1000 USD/ton.
