包裝盒是我們?nèi)粘I钪薪?jīng)常看到的日用品。每個(gè)包裝盒都有自己的質(zhì)量,檢查包裝盒質(zhì)量的方法是測(cè)量包裝盒的抗壓強(qiáng)度。包裝盒抗壓強(qiáng)度是許多商品包裝要求的重要質(zhì)量指標(biāo)。測(cè)試時(shí),將瓦楞包裝盒放在兩塊壓板之間,加壓至包裝盒塌陷時(shí)的壓力,即包裝盒定做抗壓強(qiáng)度。
Packing box is a commodity we often see in our daily life. Each packing box has its own quality. The method to check the quality of the packing box is to measure the compressive strength of the packing box. The compressive strength of packing box is an important quality index for many commodity packaging requirements. During the test, place the corrugated packing box between two pressing plates and pressurize it to the pressure when the packing box collapses, that is, the customized compressive strength of the packing box.
包裝盒定做需要一定的抗壓強(qiáng)度,因?yàn)槎逊旁诘讓拥陌b盒在貨物包裝后的儲(chǔ)存和運(yùn)輸過(guò)程中受到上層包裝盒的壓力,所以它們必須具有適當(dāng)?shù)目箟簭?qiáng)度,以免倒塌。作為日常生活中常用的包裝產(chǎn)品之一,無(wú)論是哪種包裝盒,其緩沖效果都很好,生產(chǎn)成本相對(duì)較低,適應(yīng)性強(qiáng)。在產(chǎn)品的儲(chǔ)運(yùn)和商品的包裝中非常常見(jiàn)。包裝盒的抗壓能力會(huì)直接影響包裝中的產(chǎn)品,那么影響包裝盒抗壓能力的因素有哪些呢?
Customized packing boxes need a certain compressive strength, because the packing boxes stacked at the bottom are under the pressure of the upper packing boxes during storage and transportation after goods packaging, so they must have appropriate compressive strength to avoid collapse. As one of the commonly used packaging products in daily life, no matter what kind of packaging box, it has good cushioning effect, relatively low production cost and strong adaptability. It is very common in product storage and transportation and commodity packaging. The compressive capacity of the packaging box will directly affect the products in the packaging. What are the factors affecting the compressive capacity of the packaging box?
影響包裝盒定做抗壓強(qiáng)度的因素包括原材料質(zhì)量、紙板水分、包裝盒類(lèi)型、印刷和開(kāi)松、加工過(guò)程中的偏差。以下為大家詳細(xì)介紹:原材料的質(zhì)量,原紙是決定包裝盒抗壓強(qiáng)度的決定性因素,但瓦楞紙板生產(chǎn)過(guò)程中不允許忽視其他條件的影響,如膠粘劑用量、高沖擊浸漬、涂布、復(fù)合加工等;紙板的水分:包裝盒是由含水量較高的瓦楞紙板制成,或者長(zhǎng)期存放在潮濕的環(huán)境中,會(huì)降低其抗壓強(qiáng)度。纖維是一種吸水劑。雨季空氣濕度大時(shí),紙板含水率與大氣環(huán)境的關(guān)系非常重要。
The factors affecting the customized compressive strength of packaging box include the quality of raw materials, moisture of paperboard, type of packaging box, printing and loosening, and deviation in processing. The following is a detailed introduction: the quality of raw materials and base paper are the decisive factors determining the compressive strength of packaging boxes, but it is not allowed to ignore the influence of other conditions in the production process of corrugated board, such as adhesive dosage, high impact impregnation, coating, composite processing, etc; Moisture of paperboard: the packing box is made of corrugated paperboard with high moisture content, or it will reduce its compressive strength if it is stored in a humid environment for a long time. Fiber is a water absorbent. When the air humidity is high in rainy season, the relationship between paperboard moisture content and atmospheric environment is very important.
包裝盒類(lèi)型:箱型是指箱體的類(lèi)型和同類(lèi)型箱體的尺寸比例,對(duì)抗壓強(qiáng)度有顯著影響。部分白卡紙便攜紙袋采用雙層瓦楞紙板制作,抗壓強(qiáng)度較同規(guī)格單層箱明顯提高。相同條件下,盒子越高,穩(wěn)定性越差,抗壓強(qiáng)度越低。印刷和開(kāi)啟:印刷會(huì)降低包裝盒的抗壓強(qiáng)度。有通風(fēng)要求的產(chǎn)品在盒體表面開(kāi)孔,或者在盒體側(cè)面打孔,會(huì)降低包裝盒的強(qiáng)度,尤其是開(kāi)口面積大,偏向一側(cè),影響更明顯。
Packing box type: box type refers to the type of box and the size ratio of the same type of box, which has a significant impact on the compressive strength. Some white cardboard portable paper bags are made of double-layer corrugated board, and the compressive strength is significantly higher than that of single-layer boxes of the same specification. Under the same conditions, the higher the box, the worse the stability and the lower the compressive strength. Printing and opening: printing will reduce the compressive strength of the packaging box. For products with ventilation requirements, opening holes on the surface of the box or punching holes on the side of the box will reduce the strength of the packaging box, especially if the opening area is large and biased to one side.
