Many tea bags are serrated, the effect of which means to facilitate consumers to rip open bags. We often hold a corner of the tea bag, along the sawtooth is very simple to rip open the food bag. Faced with this phenomenon, many of the eaters feel dismissive. I wonder if you've ever wondered why jagged food bags are so simple to rip off?

In fact, this problem is planned to the use of mechanics.Plastic bag ManufacturerNarration, when the object is under force, the stress condition will be changed according to the shape of the object itself, usually in the fold or sharp angle of the attack mutation, if artificially supplied a sharp angle, that place is "shortcoming."

TeaAluminum Foil Vacuum BagThe "Downside" is the manufacturer for tea bags made of serrated teeth. Food packaging is the most common plastic, plastic products have a characteristic, is in the gap without gap pull because its characteristics will not be easy to separate in the inevitable direction. Sawtooth settings is to find this breakthrough, simply reserve a serrated or cut with a little force can damage its structure easy to rip open.

What is the forming principle of tea aluminum foil bag? In fact, the composition of plastic polymer chain structure so that it has a characteristic, that is, in the chain direction can accept a large tensile force does not crack, but in the direction perpendicular to the chain is very simple to be ripped open. It's like sticking more to the stitching line, and you pull it in the direction of the line, and it must be harder to pull it off than the direction of the vertical line.
