 什么因素影響紙箱抗壓能力, 杭州鼎峰紙業包裝有限公司給大家講解一下:


1)原材料質量 


    原紙是決定紙箱壓縮強度的決定性因素,然而瓦楞紙板生產過程中其他條件的影響也不允許忽視,如粘合劑用量、楞高變化浸漬、涂布、復合加工處理等。 


2)水分 


    紙箱用含水量過高的瓦楞紙板制造,或者長時間貯顧在潮濕的環境中,都會降低其耐壓強度。纖維是一種吸水性很強的,在梅雨季節及空氣中濕度較大時,紙板中水分與大氣環境的濕平衡關系很重要。


   


3)箱型 


    箱型是指紙箱的類型和同種類型箱的尺寸比例,它們對抗壓強度有明顯的影響。有的紙箱箱體為雙層瓦楞紙板構成,耐壓強度較同種規格的單層箱明顯提高;在相同條件下,箱體越高,穩定性就越差,耐壓強度越低。


4)印刷與開孔 


    印刷會降低紙箱抗壓強度。包裝有透氣要求的商品在箱面開孔,或在箱側沖切提手孔,都會降低紙箱強度,尤其開孔面積大,偏向某一側等,影響更為明顯。 


5)加工工藝偏差渦街流量計 


    在制箱過程中壓線不當,開槽過深,結合不牢等,也會降低成紙箱耐壓強度。成品紙箱如需達到一定的強度,須做抗壓(紙箱抗壓試驗機)、環壓、堅壓、邊壓、粘合(環壓試驗機)、耐破度(破裂強度試驗機)等試驗,來評定,所出紙箱是否符合客戶要求或國家標準。

What factors affect the compressive capacity of cartons? Hangzhou Dingfeng Paper Packaging Co., Ltd. will explain to you:

1) Quality of raw materials

Base paper is the decisive factor to determine the compressive strength of cartons. However, the influence of other conditions in the production process of corrugated cardboard can not be ignored, such as the amount of adhesives, impregnation of corrugated height changes, coating, composite processing and so on.

2) moisture content

Cartons made of corrugated cardboard with excessive moisture content, or stored in humid environment for a long time, will reduce their compressive strength. Fiber is a kind of water absorbent. When the humidity in the air is high during the plum rain season, the relationship between moisture in cardboard and the humidity in the atmosphere is very important.


3) box type

Box type refers to the type of carton and the size ratio of the same type of carton. They have a significant impact on the compressive strength. Some cartons are made of double-layer corrugated cardboard, and their compressive strength is obviously higher than that of single-layer cartons of the same specifications. Under the same conditions, the higher the carton, the worse the stability and the lower the compressive strength.

4) Printing and Opening

Printing reduces the compressive strength of cartons. The strength of cardboard boxes can be reduced by opening on the surface of the box or punching and cutting the hand holes on the side of the box, especially when the area of opening is large and the side is inclined to a certain side.

5) Vortex Street Flowmeter with Processing Deviation

In the process of making cartons, improper wire pressing, deep grooving and poor combination will also reduce the compressive strength of cartons. If the finished cartons need to reach a certain strength, they must be tested for compression (carton compression testing machine), ring pressing, rigid pressing, side pressing, adhesion (ring pressing testing machine), bursting resistance (rupture strength testing machine) to assess whether the cartons meet customer requirements or national standards.
