如何识别可降解的餐盒呢？实际上，玉米淀粉颗粒生产厂家认为，其绿色环保包装应该符合三点，一是易收回，二是易处置，三是易消纳，便是容易被天然环境融合，但即使是可降解餐具，也不是短时刻能做到的。

How to identify degradable lunch boxes? In fact, the manufacturer of corn starch granules believes that their green and environmentally friendly packaging should comply with three points: easy to retrieve, easy to dispose of, easy to absorb, and easy to blend with the natural environment. However, even biodegradable tableware cannot be achieved in a short period of time.

许多降解产品宣称降解时刻为三个月到六个月，但其实这是在实验室标准环境下确认的，在天然环境下，降解受温度、湿度等多种要素影响，比如你把饭盒放到没有水的当地，那么也很难降解",在天然条件下，降解产品至少需求一年时刻降解。

Many degradation products claim to have a degradation time of three to six months, but this is actually confirmed under laboratory standard environments. In natural environments, degradation is influenced by various factors such as temperature and humidity. For example, if you place a lunch box in a place without water, it is also difficult to degrade. Under natural conditions, degradation products require at least one year of degradation.

如何选购可降解餐盒？

How to choose a biodegradable lunch box?

看密封性。一般餐盒应密封在塑料包装袋中，包装袋不该有破损，包装不严密的餐盒容易受到环境的污染，卫生得不到保证。

Check the sealing performance. Generally, lunch boxes should be sealed in plastic packaging bags, and the packaging bags should not be damaged. Food boxes with loose packaging are prone to environmental pollution and hygiene cannot be guaranteed.

看外包装。要仔细检查包装标志上是否标示了"产品名称、生产者厂名、厂址、产品履行规范、生产日期、保质期、卫生许可证"等国家规定必须标示的内容，如果标志内容标示不全或许不规范，则这样的餐盒就不要购买了。

Look at the outer packaging. It is necessary to carefully check whether the packaging label indicates the contents that must be marked according to national regulations, such as "product name, manufacturer's factory name, factory address, product performance specifications, production date, shelf life, and hygiene license". If the label content is incomplete or not standardized, such lunch boxes should not be purchased.

看盒身。质量好的餐盒盒身的色泽应均匀、概括清晰，盒口不该有显着的洼陷、起皱。看盒口。留意盒口平整、润滑，无废边、毛刺，杯身应清洁通明，厚薄均匀，无杂质、气泡、水纹，无鱼眼僵块等现象。

Look at the box body. The color of a high-quality lunch box should be uniform and clearly summarized, and the box mouth should not have significant depressions or wrinkles. Look at the box mouth. Pay attention to the smoothness and lubrication of the box mouth, without waste edges or burrs. The cup body should be clean and transparent, with uniform thickness, without impurities, bubbles, water marks, or fish eye blockages.

建议，可通过"一看、二闻、三撕"几种办法进行可降解餐具区分：一看，首先要看餐盒上是否有QS标识及编号；其次，还要看餐盒的外表是否光亮，有无杂质或黑点。一般来说，通明的塑料餐盒是运用纯聚丙烯（PP）生产的，安全系数比较高。

Suggest distinguishing degradable tableware through several methods such as "first look, second smell, and third tear": first, check if there is a QS identification and number on the lunch box; Secondly, it also depends on whether the appearance of the lunch box is bright and whether there are any impurities or black spots. Generally speaking, transparent plastic lunch boxes are produced using pure polypropylene (PP) and have a relatively high safety factor.

色彩艳丽的餐盒，有可能运用了废塑料，因而色彩越深越不安全。二摸，是要摸一摸餐盒的强度，运用收回废料或很多添加工业级碳酸钙、滑石粉生产的餐盒，强度一般都很差，轻轻一撕就决裂。三闻，是要闻一闻餐盒有无异味，合格餐盒是闻不出来味道的。

Colorful lunch boxes may have used waste plastic, making the darker the color, the less safe it is. Second touch is to touch the strength of the lunch box. The lunch box produced by recycling waste or adding industrial grade calcium carbonate or talcum powder is generally poor in strength, and can easily crack with a gentle tear. Three sniffs are to sniff the food box for any odors, and qualified food boxes cannot smell the odor.

"黑餐盒"的特色总结起来便是六句顺口溜：手捏软绵绵、轻撕就决裂、一闻冲鼻有异味、遇热变形易渗漏、手折就有白腊印、撕碎入水就下沉。大家只要记住上面的顺口溜，就可以轻松的分辩一次性餐盒是否合格了。更多相关内容就来我们网站https://www.swjjkl.com咨询吧！

The characteristics of the "black lunch box" can be summarized as six catchphrases: soft and smooth when pinched, easy to tear and crack, unpleasant smell when smelled, easy to leak when deformed when exposed to heat, white wax marks when folded, and sinking when torn into water.
