什么稱為重型紙箱，什么樣的紙箱能被稱作重型紙箱？紙箱的兩個(gè)重要物性方針，耐破強(qiáng)度，空箱抗壓，耐破強(qiáng)度的單位是kgf/cm2,是在一個(gè)平方厘米的面積的紙板上，用多大的力可以將紙板頂破，淺顯講，這是一個(gè)描述紙箱是否健壯的方針。
一般的紙箱的耐破強(qiáng)度在24kgf/cm2以下，而重型包裝紙箱一股都要超越25kgf/cm2.另一個(gè)方針是空箱抗壓：空箱抗壓的界說是紙箱成型后，其可以獨(dú)自（不靠內(nèi)裝物支撐，強(qiáng)調(diào)紙箱對內(nèi)裝物的維護(hù)）承載的重量。這個(gè)方針的單位就是kg,測試的辦法是在紙箱是加壓至多少公斤的力度時(shí)。
紙箱的形變會(huì)超越2CM,比方放置500公斤的物體在紙箱上，紙箱的變形到達(dá)2CM,即闡明這個(gè)紙箱的空箱抗壓可達(dá)500公斤。這個(gè)方針是紙箱在堆疊時(shí)參看的，重型紙箱的界說：重型紙箱的二項(xiàng)方針必定要高，質(zhì)量必定要好，作者了解此二項(xiàng)方針，耐破強(qiáng)度要大于25kgf/cm2,空箱抗壓要大于2000公斤。
到達(dá)這樣的方針才能在功用是與一厘米厚的木板附近，可以取代工箱供客戶運(yùn)用。重型紙箱的分類與優(yōu)缺點(diǎn)：市面上的AAA瓦紙箱，由三個(gè)A楞組成，面紙與底紙的基重達(dá)280克以上，瓦楞芯紙箱在170克以上，利益：功用牢靠，在用戶中已贏得信賴。可以替代大部分木質(zhì)包裝。
What is called a heavy carton, and what kind of carton can be called a heavy carton? The two important physical properties of cartons are bursting strength, compression resistance of empty cartons, and the unit of bursting strength is kgf/cm2, which is how much force can be used to break the cardboard on an area of one square centimeter. In simple terms, this is a policy to describe whether the carton is robust.
The bursting strength of ordinary cartons is less than 24kgf/cm2, while that of heavy-duty packaging cartons is more than 25kgf/cm2 Another policy is empty container compression resistance: the definition of empty container compression resistance is the weight that the carton can carry alone (not supported by the contents, emphasizing the maintenance of the contents of the carton) after it is formed. The unit of this policy is kg. The test method is when the carton is pressurized to how many kilograms.
the deformation of the carton will exceed 2cm. For example, if 500 kg of objects are placed on the carton, the deformation of the carton will reach 2cm, which means that the compression resistance of the empty carton can reach 500 kg. This policy is referred to when stacking cartons. The definition of heavy cartons: the two policies of heavy cartons must be high and the quality must be good. The author understands these two policies, the bursting strength should be greater than 25kgf/cm2, and the compression resistance of empty cartons should be greater than 2000 kg.
only when such a policy is reached, can it be used by customers near the wood board with a thickness of one centimeter, instead of working boxes. Classification and advantages and disadvantages of heavy-duty cartons: AAA corrugated cartons on the market are composed of three A-lines. The base weight of face paper and base paper is more than 280 grams, and the corrugated core carton is more than 170 grams. Benefits: reliable function, which has won trust among users. It can replace most wooden packaging.
