選擇可降解的一次性外賣打包盒是一項重要的決策，它不僅關(guān)系到環(huán)境保護(hù)，還涉及到食品的安全和質(zhì)量。以下是一些選擇可降解一次性外賣打包盒的要點：

　　Choosing biodegradable disposable takeaway packaging boxes is an important decision that not only concerns environmental protection, but also involves food safety and quality. Here are some key points for choosing biodegradable disposable takeaway packaging boxes:

　　一、考慮材料的可降解性

　　1、 Consider the degradability of materials

　　紙質(zhì)材料：紙質(zhì)餐盒是一種常見的可降解外賣打包盒材料。我國的外賣包裝經(jīng)歷了發(fā)泡餐盒 ——PP 塑料餐具 —— 可降解紙質(zhì)餐盒三個階段。紙質(zhì)餐盒具有一定的強度，可以承受食物的重量，同時在自然環(huán)境中相對容易降解。例如，上海市發(fā)布和實施的 T/31SAFCM004-2018《餐飲服務(wù) (網(wǎng)絡(luò)) 外賣 (外帶) 用紙碗通用技術(shù)要求》旨在推動消費市場使用可降解外賣紙碗替代外賣塑料送餐盒，減少塑料送餐盒和包裝材料產(chǎn)生的環(huán)境污染。

　　Paper material: Paper meal boxes are a common biodegradable food delivery packaging material. Our country's food delivery packaging has gone through three stages: foam meal boxes, PP plastic tableware, and biodegradable paper meal boxes. Paper meal boxes have a certain strength, can withstand the weight of food, and are relatively easy to degrade in natural environments. For example, the T/31SAFCM004-2018 "General Technical Requirements for Food and Beverage Service (Online) Takeout (Takeout) Paper Bowls" released and implemented by Shanghai aims to promote the use of biodegradable takeaway paper bowls instead of plastic delivery boxes in the consumer market, reducing environmental pollution caused by plastic delivery boxes and packaging materials.

　　植物纖維材料：一些外賣打包盒采用植物纖維制成，如以植物葉子為原料的全食品可降解餐盒。這種餐盒純自然無污染，通過與落葉回收站合作，可以獲得充足的高質(zhì)量原材料，取之于自然，同時回歸自然。

　　Plant fiber materials: Some takeaway packaging boxes are made of plant fibers, such as whole food biodegradable meal boxes made from plant leaves. This type of food box is pure natural and pollution-free. By cooperating with a leaf litter recycling station, we can obtain sufficient high-quality raw materials, take them from nature, and return to nature at the same time.

　　生物降解塑料：生物降解塑料是一種在特定環(huán)境下可以被微生物分解的塑料。例如，從蝦殼中提取的可降解生物聚合物材料殼聚糖，具有生物相容性、生物降解性、無毒等優(yōu)點，可用于制作薄膜。

　　Biodegradable plastics: Biodegradable plastics are plastics that can be decomposed by microorganisms in specific environments. For example, chitosan, a biodegradable biopolymer material extracted from shrimp shells, has advantages such as biocompatibility, biodegradability, and non toxicity, and can be used to make thin films.

　　二、關(guān)注食品安全性

　　2、 Pay attention to food safety

　　衛(wèi)生標(biāo)準(zhǔn)：選擇符合國家衛(wèi)生標(biāo)準(zhǔn)的外賣打包盒至關(guān)重要?？山到獠秃袘?yīng)在生產(chǎn)過程中嚴(yán)格控制衛(wèi)生條件，避免有害物質(zhì)的殘留。例如，采用 CBL-ZF80/65 雙層復(fù)合擠出吸塑成型機制備的覆膜一次性快餐盒，按照國標(biāo) GB18006.1-2009 檢測其衛(wèi)生理化性能，結(jié)果表明覆膜快餐盒在重金屬含量、脫色試驗等方面表現(xiàn)良好。

　　Hygiene standards: It is crucial to choose takeaway packaging boxes that meet national hygiene standards. Biodegradable food containers should strictly control hygiene conditions during the production process to avoid the residue of harmful substances. For example, the laminated disposable fast food box prepared by the CBL-ZF80/65 double-layer composite extrusion and vacuum forming mechanism was tested for its hygiene and physicochemical properties according to the national standard GB18006.1-2009. The results showed that the laminated fast food box performed well in heavy metal content, decolorization test, and other aspects.

　　隔離性能：外賣打包盒應(yīng)具有良好的隔離性能，防止食物與外界環(huán)境相互影響?？山到獠牧显诒ＷC隔離性能的同時，也要確保不會對食物的味道和質(zhì)量產(chǎn)生不良影響。

　　Isolation performance: Takeout packaging boxes should have good isolation performance to prevent food from interacting with the external environment. Degradable materials should not only ensure isolation performance, but also ensure that they do not have adverse effects on the taste and quality of food.

　　三、評估包裝的實用性

　　3、 Evaluate the practicality of packaging

　　強度和耐用性：盡管是一次性使用，但外賣打包盒也需要有足夠的強度來承受食物的重量和運輸過程中的壓力。紙質(zhì)餐盒在這方面可能需要通過特殊的設(shè)計和加工來提高強度。

　　Strength and durability: Although disposable, takeaway packaging boxes also need sufficient strength to withstand the weight of food and the pressure during transportation. Paper meal boxes may require special design and processing to enhance their strength in this regard.

　　密封性：良好的密封性可以防止食物泄漏和外界異味的進(jìn)入。可降解材料的密封性可能需要通過特殊的密封設(shè)計或添加密封材料來實現(xiàn)。

　　Sealing: Good sealing can prevent food leakage and the entry of external odors. The sealing performance of biodegradable materials may require special sealing designs or the addition of sealing materials.

　　尺寸和形狀：根據(jù)不同的食物類型和外賣訂單需求，選擇合適尺寸和形狀的外賣打包盒。例如，對于液體食物，需要選擇具有良好密封性和防漏性能的容器；對于固體食物，可以選擇更加方便堆疊和運輸?shù)男螤睢?/p>

　　Size and shape: Choose the appropriate size and shape of takeaway packaging box according to different food types and takeaway order requirements. For example, for liquid food, it is necessary to choose containers with good sealing and leak proof properties; For solid foods, you can choose shapes that are more convenient for stacking and transportation.

　　四、考慮成本因素

　　4、 Consider cost factors

　　價格：可降解外賣打包盒的價格可能會比傳統(tǒng)塑料餐盒略高。在選擇時，需要綜合考慮成本和環(huán)保效益。一些可降解材料的成本可能會隨著技術(shù)的進(jìn)步和市場需求的增加而逐漸降低。

　　Price: The price of biodegradable takeaway packaging boxes may be slightly higher than traditional plastic meal boxes. When making a choice, it is necessary to consider both cost and environmental benefits comprehensively. The cost of some biodegradable materials may gradually decrease with technological advancements and increasing market demand.

　　可持續(xù)性成本：除了直接的購買成本，還需要考慮可持續(xù)性成本。例如，使用可降解餐盒可能會減少對環(huán)境的污染，降低后期的處理成本。同時，一些可降解材料可以通過回收和再利用來降低成本。

　　Sustainability costs: In addition to direct purchase costs, sustainability costs also need to be considered. For example, using biodegradable meal boxes may reduce environmental pollution and lower later processing costs. Meanwhile, some biodegradable materials can be recycled and reused to reduce costs.
