一次性餐盒廣為使用量有增無減。上班族、學生是使用一次性餐盒的主要人群,記者了解到,大部分人都知道一次性餐盒不管是從衛生角度還是環保角度都存在著諸多爭議,然而就是貪圖其方便,才會一直使用。
Disposable lunch boxes are widely used, and their use is increasing. Office workers and students are the main people who use disposable lunch boxes. The reporter learned that most people know that disposable lunch boxes have many disputes whether from the perspective of health or environmental protection. However, they will always use them for their convenience.
現今市面上的一次性餐盒并不是全都符合國家標準,長期使用不合格的餐盒是會對身體帶來不好影響的,自備飯盒才是選擇。用塑料制成的一次性餐盒主要有PP聚丙烯和PS聚苯乙烯兩種,均無毒牲,無味無嗅,PP較柔軟。
Nowadays, the disposable lunch boxes on the market are not all in line with national standards. The long-term use of unqualified lunch boxes will have a bad impact on the body, and self-contained lunch boxes are the choice. Disposable lunch boxes made of plastic mainly include PP polypropylene and PS polystyrene, which are non-toxic, tasteless and odorless, and PP is soft.
一般PP使用溫度是-6度至+120度,所以特別適合盛裝熱飯熱菜,可在微波爐里加熱,甚或可在蒸氣柜里蒸煮,改性的PP其使用溫度可控制在-18度至+110度,這種PP所制成的飯盒除了可加熱至100度使用外,更可放入冰箱冷藏使用。
Generally, the service temperature of PP is - 6 ° C to + 120 ° C, so it is especially suitable for holding hot meals and dishes. It can be heated in the microwave oven or even boiled in the steam cabinet. The service temperature of modified PP can be controlled from - 18 ° C to + 110 ° C. In addition to heating to 100 ° C, the lunch box made of PP can be put into the refrigerator for refrigeration.
PS較硬,且透明,但易撕裂,PS在使用溫度達75度時開始變軟,所以不適宜盛裝熱飯熱菜,但PS的低溫性能很好,是冰淇淋好的包裝材料。有些飯盒工廠為了降低成本,用PP做盒子,用PS做盒蓋,好處是蓋子透明,且PS較硬,可以用較薄片材制成,降低成本,但這種設計消費者一定明白兩種材料的差異,切記不要把整盒飯連蓋子一并放入微波爐中加熱。
PS is hard and transparent, but it is easy to tear. PS starts to soften when the service temperature reaches 75 degrees, so it is not suitable for hot rice and dishes, but PS has good low-temperature performance and is a good packaging material for ice cream. In order to reduce the cost, some lunch box factories use PP as the box and PS as the box cover. The advantage is that the cover is transparent and PS is hard. It can be made of thinner sheets to reduce the cost. However, consumers must understand the differences between the two materials and remember not to put the whole box of lunch with the cover into the microwave oven for heating.
