Title
(EN) FOAM SHEET COMPRISING SKIN LAYER, METHOD FOR MANUFACTURING SAME, AND FOOD CONTAINER COMPRISING SAME
(ZH) 包括表面层的发泡片材、其制备方法及包括其的食品容器
Abstract
(EN)
The present invention relates to a foam sheet comprising a skin layer, a method for manufacturing same, and a food container comprising same, and can provide a food container exhibiting excellent surface uniformity by comprising a skin layer on a foam layer, excellent thermoformability by comprising a foam layer having a degree of crystallization in a predetermined range, and excellent adhesiveness to a lid and low rate of change in volume.

(ZH)
本发明涉及包括表面层的发泡片材、其制备方法及包括其的食品容器,在发泡层上包括表面层,从而可提供如下食品容器,即,包括具有优异的表面均匀性及规定范围的结晶度的发泡层,由此具有优异的热成型性和引线粘结性且体积变化率低。
