See QXD brand stretch film has played 4-6 times the elongation rate, is not it very puzzling, what does that mean?
The so-called elongation refers to the ratio of a fixed length of one-inch film that can be stretched (stretched) by external force. 4-6 times the elongation refers to the 1 meter winding stretch film under normal circumstances can pull out the length of 4-6 meters!
So much elongation of stretch film what good is it? Perhaps you know very well that the high elongation rate means that the telescopic performance is good, so that when fixing the tray or carton, it will be firmer, and the contact with the product will be even closer, which will save space and costs! The stretch film with good elongation has larger contact area with the product and will not loosen. This way, when the worker is using it, it will not be wound more than a few times because it can't be seen tightly, which can save the number of use. The more accurate point is to save the packaging for you. Material costs! Elongation is good, moderate thickness can be selected, a roll of film of the same weight can make longer meters, save money! Such as hand-wrap film, QXD brand stretch film is generally 18mil thickness, and the market there are many need to do 23mil-25mil thickness is available!
When selecting the wrapping film , the stretchability of the wrapping film must be taken into consideration . Naturally, the toughness of the wrapping film is high. If the toughness is not good, do not say 4-6 times the distance, that is, if it is several tens of centimeters, it will be cut off. , Do not believe you try. The toughness of the stretch film is more secure after the product is fixed, and the product will have more layers of protection!
