Froða er nú borið á í mörgum umbúðum, sem gegnir hlutverki hægs titrings og kemur í veg fyrir að skemmdir hlutar skemmist af ytri vélrænni krafti.
Foam is made of shape molding machine. Do you know the working principle of shape molding machine? Let's have a look.
1. Skilgreining á formmótunarvél
Þegar það er notað í vörupökkun er efnið sem getur myndað plastfroðu sprautað inn í bilið milli ílátsins og filmufóðraða innréttingarinnar og vélin er mynduð með efnahvörfum til að mynda froðupúðaefni sem er þétt pakkað inni.

♥ Foam will not emerge from the sky. It must be made by special process for foaming equipment.
♥ Foaming equipment is a device that can make a certain concentration of water solution (foaming agent) into foam.
♥ Foaming agent itself can not automatically become a bubble, it must through foam machine's mechanical function can become a bubble.
♥ The foaming equipment itself can not produce bubbles without any cost. It disperses the air into the foaming agent aqueous solution evenly and realizes the contact surface of the liquid gas as large as possible, so that the surface active substances in the foaming agent form a double electric layer on the liquid film surface and encircling the air, forming bubbles.
♥ Foaming machine and foaming agent are a technical system that cooperate with each other and can not play a role alone.
