一次性紙餐盒環(huán)保嗎?如何使用?
來源:mingmingda.com 發(fā)布時間:2023-04-14 瀏覽次數(shù):122
一次性紙餐具是以紙為基材,表面覆蓋有石蠟、聚乙烯涂層等,用于食品包裝或盛裝冷熱飲料和冷熱食品的容器,紙餐具按加工原料可分為紙板紙餐具、紙漿模塑紙餐具、淋膜紙餐具。
Disposable paper tableware is made of paper as the substrate, covered with paraffin, polyethylene coating, etc., and used for food packaging or containers for cold and hot beverages and food. Paper tableware can be divided into cardboard paper tableware, pulp molded paper tableware, and coated paper tableware according to the processing materials.
一次性紙餐盒相比其他一次性餐盒,確實更環(huán)保,因為它通常使用可回收和可降解的紙材制成,使用后可進行再利用或者回收處理。但是,使用一次性餐盒作為日常餐盒的選擇還是有其局限性和不足的,這是因為:
Disposable paper lunch boxes are indeed more environmentally friendly compared to other disposable lunch boxes, as they are usually made of recyclable and degradable paper materials that can be reused or recycled after use. However, using disposable lunch boxes as a choice for daily meals still has its limitations and shortcomings, as:
生產(chǎn)一次性紙餐盒需要消耗大量的森林資源和能源。
Producing disposable paper lunch boxes requires a significant amount of forest resources and energy consumption.
大多數(shù)一次性紙餐盒被污染過,不能再次使用,容易被丟棄在自然環(huán)境中,造成環(huán)境污染。
Most disposable paper lunch boxes have been contaminated and cannot be reused, which can easily be discarded in the natural environment and cause environmental pollution.
由于一次性紙餐盒不耐水,容易變形,所以需要注意使用時不要遇水或者太多油脂。
Due to the lack of water resistance and easy deformation of disposable paper lunch boxes, it is necessary to be careful not to come into contact with water or too much grease during use.
為避免污染,一次性紙餐盒應該選擇環(huán)保型紙質(zhì)餐盒,避免使用過厚的涂膜紙餐盒和未充分被回收的紙餐盒。
To avoid pollution, disposable paper lunch boxes should be environmentally friendly, avoiding the use of thick coated paper lunch boxes and paper lunch boxes that have not been fully recycled.
一次性紙餐盒
紙質(zhì)餐具的制作一般是先模切紙張,然后彎折接合,后熱合成型。由于紙張材質(zhì)本身具有較好的滲透性能,因此制作餐具對于原料和工藝要求特別嚴格,控制不當就會出現(xiàn)餐具軟塌,或者食物從接縫處滲漏等問題。
The production of paper tableware generally involves first die-cutting the paper, then bending and joining it, and then forming it by heat sealing. Due to the good permeability of paper material itself, the requirements for raw materials and processes in making tableware are particularly strict. Improper control can lead to problems such as tableware collapse or food leakage from joints.
為了測試紙碗的物理安全,國家標準設計了滲漏、抗壓等指標考核紙餐具的使用性能。耐滲漏的具體測試方法是在一次性紙餐具中加入(90±5)℃熱水或者油水混合物,以模擬實際食品。加液高度要到餐具口沿下約6mm處,然后將餐具放在一塊干玻璃板或平板上,靜置30min觀察玻璃(平)板上是否有滲漏的水或油印,無滲、漏才算合格。
In order to test the physical safety of paper bowls, national standards have designed indicators such as leakage and pressure resistance to assess the performance of paper tableware. The specific test method for leakage resistance is to add (90 ± 5) ℃ hot water or oil-water mixture to disposable paper tableware to simulate actual food. The liquid should be added to a height of about 6mm below the edge of the tableware mouth, and then the tableware should be placed on a dry glass plate or flat plate. Let it stand for 30 minutes to observe whether there is any leakage of water or oil on the glass (flat) plate. Only if there is no leakage or leakage can it be considered qualified.
一次性紙餐具在盛裝食物時要有一定的硬度,才能在使用中不變形坍塌。為了測試紙餐盒抵御外力作用的能力,標準設計了抗壓強度的指標,通過在樣品上下不斷增加壓力的方式測試產(chǎn)品終被壓潰的力值。這種測試能很好的反映產(chǎn)品的力學性能。
Disposable paper tableware must have a certain hardness when containing food, in order to not deform or collapse during use. In order to test the ability of paper lunch boxes to resist external forces, the standard designed an indicator of compressive strength, which tests the final crushing force of the product by continuously increasing pressure on the sample. This test can well reflect the mechanical properties of the product.
使用一次性紙餐盒需要注意環(huán)保原則,避免浪費,避免污染,盡可能選擇可回收和可降解的環(huán)保型紙質(zhì)餐盒,同時也需要注意使用時避免遇水或油脂,以確保合理使用。歡迎您隨時來我們網(wǎng)站http://mingmingda.com咨詢!
When using disposable paper lunch boxes, it is necessary to pay attention to environmental principles, avoid waste, avoid pollution, and try to choose recyclable and biodegradable environmentally friendly paper lunch boxes.
