一、阻隔功能
1、 Barrier function
纸和纸板属于多孔性纤维材料，对水分、气体、光线、油脂等具有必定程度的渗透性，且其阻隔性受温湿度的影响较大，可以经过恰当的外表加工来满意其阻隔功能的要求。
Paper and paperboard are porous fiber materials, which have a certain degree of permeability to moisture, gas, light, grease and so on, and their barrier property is greatly affected by temperature and humidity, so they can be processed properly to meet the requirements of barrier function.
二、加工功能
2、 Processing function
纸和纸板具有杰出的加工功能，可折叠处理，并可采用多种封合方法，简单加工成具有各种功能的包装容器，简单实现机械化加工操作。别的经过恰当的外表加工处理，可以为纸和纸板供给必要的防潮性、防虫性、阻隔性、热封性、强度及物理功能等，扩大其使用范围。
Paper and paperboard have outstanding processing function, folding processing, and can use a variety of sealing methods, simple processing into a variety of functional packaging containers, simple realization of mechanical processing operation. After proper surface processing, paper and paperboard can be provided with necessary moisture-proof, insect proof, barrier, heat sealing, strength and physical functions, so as to expand its application range.
三、机械功能
3、 Mechanical function
纸和纸板具有必定的强度、挺度和机械适应性，它的强度巨细首要决定于纸的材料、质量、厚度、加工工艺、外表情况及必定的温湿度条件等;别的纸还具有必定的折叠性、弹性及撕裂性等，适合制作成型包装容器或用于裹包。
Paper and paperboard have a certain strength, stiffness and mechanical adaptability. Its strength mainly depends on the paper material, quality, thickness, processing technology, appearance and certain temperature and humidity conditions; other paper also has certain folding, elasticity and tearing properties, which are suitable for forming packaging containers or wrapping.
四、卫生功能
4、 Health and safety function
在纸的加工过程中，尤其是化学法制浆，通常会残留必定的化学物质，因而有必要根据包装内容物来正确合理选择各种纸和纸板。
In the process of paper processing, especially in chemical pulping, there are always some chemical residues. Therefore, it is necessary to select various kinds of paper and paperboard according to the contents of the package.
五、印刷功能
5、 Printing function
纸和纸板吸收和粘结油墨的能力较强，印刷功能好，因而在包装上常用作印刷外表。纸和纸板的印刷功能首要决定于外表平滑度、施胶皮、弹性及粘结力等。
Paper and paperboard have strong ability to absorb and bond ink and have good printing function, so they are often used as printing appearance on packaging. The printing function of paper and paperboard mainly depends on the surface smoothness, rubber application, elasticity and adhesion.
