Printed Paper Box Materials<\/h1>\n

For the custom paper box<\/a>, the paper printed box<\/a> is usually made of 4 kinds of paperboards. The SBS paperboard<\/a> is white color inside and outside, which is widely used for the cosmetic paper boxes<\/a>. The CUK, also referred to as SUS, is white color outside and kraft brown color inside, which is widely used for the beer carriers, beer cartons, beverage paper boxes<\/a>. The kraft paperboard<\/a> is kraft brown color inside and outside. It is used to make the kraft paper box<\/a> and corrugated printed box<\/a>. The CCNB paperboard<\/a> is white color outside and grey color inside.<\/p>\n

In China, the thickness of the paperboard is measured in millimeters, while point is used in USA, which is abbreviated to pt. The formulas below can be used for the conversion of the 2 units.<\/span><\/p>\n

1 inch =25.4mm\u00a0= 1000 pt.\u00a0<\/span><\/p>\n

1 pt = 0.0254mm<\/span><\/p>\n

For example, 60pt=60*0.0254mm=1.524mm. The 60pt chipboard in USA refers to the 1.5mm greyboard in China, which is very ideal for the small rigid paper boxes<\/a>. When you need a strong rigid box, 80pt chipboard can be used, which is 2mm thick greyboard in China.<\/span><\/p>\n
