近年来,热收缩包装这一形式因其特有的贴体、美观、防潮、防伪而倍受青睐,被广泛应用于化妆品、礼品、茶叶、酱醋、矿泉水及其他的产品包装上。但是令众多收缩机生产厂家头痛的是:矿泉水、果酱等饮料食品在带液的情况下进行标签膜收缩或全收缩包装,因其温差大、瓶体导热快,往往效果不理想(收缩膜表面起皱、瓶体卧置传送,易漏液损坏热源等)。许多饮料生产厂家只好将玻璃瓶或矿泉水瓶浸在沸水中或用电吹风吹热风来解决,劳动强度大、效率差又大量浪费能源。 In recent years, this form of shrink packaging due to its unique body, beautiful, moisture-proof, security and much favored, is widely used in cosmetics, gifts, tea, vinegar sauce, mineral water and other product packaging. However, many manufacturers have a headache is shrinking: mineral water, jam and other beverage products in the case of liquid with a label shrink film or shrink packaging, because of its large temperature difference, the bottle heat conduction, the effect is often not ideal (shrink film Surface wrinkling, lying on the body to send, easy to damage the heat source, etc.). Many beverage manufacturers have to dip glass bottles or mineral water bottles in boiling water or hot air blow to solve, labor-intensive, inefficient and a lot of waste of energy.
