Knowledge sharing and summary of stretch film  

The biggest bottleneck in sales is that you can’t ask critical questions, but if you ask too much, customers will find it too annoying. If you ask too little, you can’t figure out the situation. If you simplify the problem, you can understand the customer's needs and the crux of the problem.

For the customers who use the wrapping machine, the buyer is absolutely familiar with the stretch film, because the stretch film cannot be bypassed when the wrapping machine is used, and the stretch film is the golden partner of the pallet wrapping machine, although the packaging machine can use other packaging machines. Materials are used for packaging, but stretch film is the "favorite" of packaging. In terms of cost and consumption, the use of stretch film packaging is the most economical; as we usually say 1:200, 1:300 ...Do you really understand? If you don't understand, then you understand now.

The so-called treasure knife with hero, high-quality wrapping film should be matched with high-quality wrapping machine, our packaging machine is the best of high-quality machines, and then the same machine should also be matched with high-quality film to get twice the result with half the effort. As for how to calculate the most economical.  

4Q- Ask 4 key questions for the customer's on-site packaging    
 

Q1- The perimeter of the pallet (length + width)*2  

Q2- The number of turns of the actual package-needs to be calculated visually  

Q3- The weight of the wrapped stretch film-cut the wrapped stretch film to weigh  

Q4- The thickness of stretch film  

With the above information. We can use the formula to calculate the true pre-stretching of the stretch film on the equipment.  

For example:  

Q1- Pallet size-1.2 meters X 1.2 meters, the circumference is 4.8 meters  

Q2- Actually wrapped 20 laps  

Q3- 400g=0.4kg  

Q4- 20 microns = 0.020mm  

Weight of unstretched stretch film  

-Q1 X Q2 X Q4 X density 0.92  

4.8m X 20 X0.020mm X0.92 = 1.77Kg  

Real pre-stretch  

1.77 ：0.4(Q3)  

4.43 :1; 343% pre-stretch  

If you want to replace the current 20-micron film with a thinner film, you must consider whether you can meet the 343% requirement.
