The acrylic material is injection bottle, which has poor chemical resistance. Generally, it can't be filled directly with paste. It needs to be separated by inner gallbladder. The filling is not easy to be too full. It prevents paste from entering between inner gallbladder and acrylic bottle, so as to avoid cracking. In transportation, the packaging requirements are higher.
