  塑料型

  Plastic type

  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,均無毒性無味無嗅,PP較柔軟,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。

  Disposable food containers made of plastic mainly include PP polypropylene and PS polystyrene, both of which are non-toxic, odorless, and tasteless. PP is relatively soft, and the general temperature range for PP is -6 ° C to+120 ° C, making it particularly suitable for holding hot rice and vegetables. It can be heated in a microwave or even steamed in a steam oven. The modified PP can be controlled to a temperature range of -18 ° C to+110 ° C. These lunch boxes made of PP can not only be heated to 100 ° C for use, but also stored in a refrigerator for refrigeration.20230308114946213.jpg

  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,是冰淇淋最好的包裝材料。

  PS is relatively hard and transparent, but it is easy to tear. When used at a temperature of 75 degrees, PS begins to soften, so it is not suitable for holding hot meals and dishes. However, PS has good low-temperature performance and is the best packaging material for ice cream.

  有些飯盒為了降低成本,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,但這種設計消費者必須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。

  Some lunch boxes use PP for the box and PS for the lid in order to reduce costs. The advantage is that the lid is transparent and PS is harder, which can be made of thinner sheets to reduce costs. However, consumers must understand the difference between the two materials in this design and remember not to heat the entire box of lunch with the lid in a microwave oven.

  紙板型

  Cardboard type

  紙板快餐盒是以300-350克的漂白硫酸鹽木漿紙板為原料,通過類似鈑加工的沖壓成型工藝進行模切黏合或模切壓制定型等工序制成,為防止其滲油或滲水要在其表面淋膜或施用化學助劑,在生產與使用過程中對人體是無毒無副作用的,但對于紙板的質量要求較高隨之成本也提高。

  The cardboard fast food box is made from 300-350 grams of bleached kraft pulp cardboard as raw material, which is processed through stamping and forming processes similar to sheet metal processing, such as die-cutting bonding or die-cutting compression shaping. To prevent oil or water leakage, a film or chemical additives should be applied on its surface. It is non-toxic and has no side effects on the human body during production and use, but the quality requirements for cardboard are high, and the cost also increases.

  淀粉型

  Starch type

  以淀粉為原料的可食用型快餐盒,顧名思義它是以淀粉類植物為原料加入膳食纖維和其他可食用類助劑經攪拌捏合而成,它采用生物復配聚糖交聯鈣離子螯合等技術精制而成,由致密層、內防水層、膠網層和外防水層四部分構成。

  An edible fast food box made from starch, as the name suggests, is made by mixing and kneading starch plants with dietary fiber and other edible additives. It is refined using techniques such as biological compound polysaccharide cross-linking calcium ion chelation, and consists of four parts: a dense layer, an inner waterproof layer, a rubber mesh layer, and an outer waterproof layer.

  紙漿模塑型

  Pulp molding type

  將木紙漿或蘆葦蔗渣麥秸稻草等一年生草本植物纖維紙漿經碎漿和凈化,加入適量無毒化學助劑,成型干燥整型定型切邊消毒,制成產品的美觀性并不高,同時也會增加廢水的污染。

  The fiber pulp of annual herbaceous plants such as wood pulp, reed, sugarcane bagasse, wheat straw, and rice straw is crushed and purified, and an appropriate amount of non-toxic chemical additives are added to form, dry, shape, cut and disinfect the edges. The beauty of the resulting product is not high, and it also increases the pollution of wastewater.

  植物纖維型

  Plant fiber type

  在環(huán)保優(yōu)勢上植物纖維餐盒具有明顯的優(yōu)勢,它是以稻草稻谷殼甘蔗渣等提取的植物纖維作為原料加入成型劑黏合劑耐水劑等助劑,攪拌通過成型機成型加以干燥整型消毒等后期加工而成,這些農業(yè)的下腳料可成為工業(yè)原料有助于農業(yè)資源的綜合利用。

  Plant fiber meal boxes have obvious advantages in environmental protection. They are made from plant fibers extracted from rice straw, rice husks, sugarcane bagasse, and other materials, and added with molding agents, adhesives, water-resistant agents, and other additives. They are mixed and molded by a molding machine, dried, shaped, disinfected, and processed later. These agricultural waste materials can become industrial raw materials, which helps to comprehensively utilize agricultural resources.

  可降解塑料餐盒

  Degradable plastic lunch box

  此類餐盒的制造原料是可降解塑料,所謂可降解塑料就是在塑料的生產過程中加入一定量的添加劑如光敏劑淀粉等原料,這樣可降解塑料制品在使用完并廢棄在大自然中暴露三個月后,可由完整的形狀分解成碎片,因而至少在視覺上改善了環(huán)境,但這項技術最大的缺陷是這些碎片不能繼續(xù)降解,只不過是由大片變成小片塑料,不能從根本上勝任消除白色污染的任務。

  The manufacturing material of this type of food box is biodegradable plastic, which refers to the addition of a certain amount of additives such as photosensitizer starch during the production process of plastic. After being used and exposed to nature for three months, biodegradable plastic products can break down from their complete shape into fragments, at least visually improving the environment. However, the biggest drawback of this technology is that these fragments cannot continue to degrade, only turning from large pieces into small pieces of plastic, which cannot fundamentally fulfill the task of eliminating white pollution.

  生物全降解餐盒

  Biodegradable food box

  生物全降解餐盒是一種比較先進的環(huán)保產品。它以淀粉為主要原料,加入一年生長期植物纖維粉和特殊的添加劑,經過化學和物理方法處理制成生物全降解快餐盒,由于淀粉是一種可生物降解天然高分子,在微生物的作用下分解為葡萄糖,最后分解為水和二氧化碳。

  Biodegradable food containers are a relatively advanced and environmentally friendly product. It uses starch as the main raw material, adds one-year growth period plant fiber powder and special additives, and is processed by chemical and physical methods to make a biodegradable fast food box. As starch is a biodegradable natural polymer, it is decomposed into glucose under the action of microorganisms, and finally into water and carbon dioxide.

  此外與其共混的材料也是全降解材料,因此可以說它對環(huán)境沒有任何影響。生產原料淀粉的主要來源可以是玉米土豆紅薯木薯等一年生長期植物。

  In addition, the material blended with it is also a fully degradable material, so it can be said that it has no impact on the environment. The main source of starch production raw materials can be one-year growing plants such as corn, potatoes, sweet potatoes, cassava, etc.

  自然生物全降解餐盒也并不是十全十美,例如生產原料大部分是糧食作物且有防霉變等問題尚待解決。

  Natural biodegradable meal boxes are not perfect, for example, most of the production materials are grain crops and there are problems such as mold resistance that need to be solved.
