滿足質量要求的紙盒

Paper boxes that meet quality requirements

除透明性以外，紙盒可以通過其結構和材料來實現(xiàn)其功能要求。按形狀分，代表性的紙盒包括屋頂盒結構紙盒、方形盒以及其他結構的紙盒。

In addition to transparency, paper boxes can meet their functional requirements through their structure and materials. According to shape, representative paper boxes include roof box structural paper boxes, square boxes, and other structural paper boxes.

再生性

Regenerative

作為代表性的紙盒有屋頂盒結構的紙盒、牛皮紙盒、牛皮飲料杯等。其結構分為聚乙烯／卡紙／聚乙烯三層。所用的卡紙從250g/㎡-400g/㎡具體根據(jù)紙盒的大小、形狀以及內容物重量來選定。

Representative paper boxes include roof box structures, kraft paper boxes, and kraft beverage cups. Its structure is divided into three layers: polyethylene/cardboard/polyethylene. The cardboard used ranges from 250g/㎡ to 400g/㎡, depending on the size, shape, and weight of the contents of the cardboard box.

這些紙盒所用的卡紙是通過擠壓機在卡紙的正反面進行聚乙烯的擠壓成型加工制成的。由于紙與聚乙烯在堿溶液當中比較容易剝離或分離，使得紙張成分的再生容易實現(xiàn)。紙盒的再生利用得以實現(xiàn)，除了上述所言的紙張成分容易再生的因素外，還有一個原因就是實際上只使用原漿來生產紙盒用卡紙。

The cardboard used in these cardboard boxes is made by extruding polyethylene on both sides of the cardboard using an extruder. Due to the easy detachment or separation of paper and polyethylene in alkaline solutions, the regeneration of paper components is easy to achieve. The recycling and utilization of paper boxes can be achieved not only due to the factors mentioned above that the paper components are easily recycled, but also because only the original pulp is actually used to produce cardboard for paper boxes.

阻隔性

barrier 

氧氣、水蒸氣以及光線是導致包裝內容物變質的原因。為了給紙盒增加有關的阻隔性能，方法之一是與鋁箔復合。此方法可以使紙盒具備阻隔氧氣、水蒸氣以及光線的功能。采用鋁箔復合的紙盒，其中的內容物可以實現(xiàn)長期保存。

Oxygen, water vapor, and light are the reasons for the deterioration of the packaging content. One method to increase the barrier performance of the cardboard box is to composite it with aluminum foil. This method can make the cardboard box have the function of blocking oxygen, water vapor, and light. The paper box is made of aluminum foil composite, and the contents can be stored for a long time.

紙邊保護結構

Paper edge protection structure

利用適合顧客需要的印刷方法，在經過擠壓機層壓加工制成的紙盒用卡紙表面進行印刷加工。主要的印刷方法包括凹印和膠印，大批量的場合采用凹印，小批量的場合采用膠印，不過有時是按滿足設計的要求來選擇印刷方法的。印刷完畢的卡紙經模壓模切制成所需的展開形狀，接著通過一臺火焰密封設備，利用其氣體火焰使聚乙烯熔融在卡紙正反面的紙邊部分，將卡紙正反面的邊緣相互粘合而制成紙盒。

Using printing methods that are suitable for customer needs, the cardboard surface of the paper box made by laminating with an extruder is printed and processed. The main printing methods include gravure printing and offset printing. Gravure printing is used in large quantities, while offset printing is used in small quantities. However, sometimes the printing method is selected based on meeting design requirements. The printed cardboard is molded and cut into the desired unfolded shape. Then, through a flame sealing device, the gas flame is used to melt polyethylene on the edges of the front and back sides of the cardboard, and the edges of the front and back sides of the cardboard are bonded together to form a paper box.

對于咖啡、飲料類的對紙具有高滲透性的內容物而言，紙盒的邊緣部一旦與飲料等接觸，就會因內物液體的滲透使紙盒的強度變差，產生泄漏乃至損壞。因此，通過粘貼紙帶或者將紙折疊來防止紙邊緣與內容物液體相接觸。通過這樣的方法，加上前面提到的增加阻隔性能的結構，保證了飲料紙杯能在常溫下的流通以及長期保存。

For coffee and beverage contents with high permeability to paper, once the edge of the paper box comes into contact with beverages, the strength of the paper box will deteriorate due to the penetration of the liquid inside, resulting in leakage and even damage. Therefore, by pasting paper tape or folding the paper to prevent the edges of the paper from coming into contact with the liquid content. Through this method, combined with the previously mentioned structure that increases barrier performance, the beverage paper cup can circulate at room temperature and be stored for a long time.

環(huán)境保護

environmental protection

使用鋁箔雖然為紙盒飲料的長期保存提供了可能，但會造成原紙的再生困難、還會導致焚燒紙容器時其中的鋁箔損壞焚燒爐的事故發(fā)生。通過采用替代鋁箔的阻隔材料，可以實現(xiàn)既能環(huán)保又能長期保存的全面要求。典型的替代用阻隔材料如EVO（ 乙烯醋酸乙烯共聚物）和硅真空鍍膜。

Although the use of aluminum foil provides the possibility for long-term preservation of paper box beverages, it can cause difficulties in regenerating the original paper and also lead to accidents where the aluminum foil inside the paper container is damaged in the incinerator during incineration. By using barrier materials that replace aluminum foil, comprehensive requirements for both environmental protection and long-term preservation can be achieved. Typical alternative barrier materials such as EVO (ethylene vinyl acetate copolymer) and silicon vacuum coating.
