外賣打包袋保溫型的設(shè)計(jì)圍繞 “減少熱量交換” 核心目標(biāo)，通過材料組合、結(jié)構(gòu)優(yōu)化與細(xì)節(jié)處理，構(gòu)建能延緩溫度流失的封閉空間。其設(shè)計(jì)需平衡保溫效果、承重能力與使用便利性，讓熱食在配送過程中保持適宜溫度，冷食維持低溫，滿足消費(fèi)者對餐品口感的需求。

　　The design of the insulated takeaway packaging bag revolves around the core goal of "reducing heat exchange". Through material combination, structural optimization, and detail treatment, a closed space that can delay temperature loss is constructed. Its design needs to balance insulation effect, load-bearing capacity, and ease of use, keeping hot food at a suitable temperature during delivery and cold food at a low temperature, meeting consumers' needs for food taste.

　　保溫材料的分層組合是保溫型打包袋設(shè)計(jì)的基礎(chǔ)，通過阻隔傳熱路徑實(shí)現(xiàn)溫度保持。外層多采用牛津布或尼龍布，這類面料密度高、耐磨性強(qiáng)，能抵御配送過程中的摩擦與輕微撞擊，表面經(jīng)防水涂層處理，可防止雨水滲透影響內(nèi)層保溫材料。中間保溫層是核心，常見材料有珍珠棉、鋁箔復(fù)合氣泡膜等 —— 珍珠棉質(zhì)地輕盈且富有彈性，內(nèi)部無數(shù)獨(dú)立氣泡能有效阻隔空氣對流，同時(shí)具備一定緩沖作用，適合盛裝湯類等易灑餐品；鋁箔復(fù)合氣泡膜通過鋁箔的反射作用阻擋熱輻射，氣泡層減少空氣傳導(dǎo)，保溫效果比珍珠棉更優(yōu)，常用于需要長時(shí)間保溫的場景。內(nèi)層通常為食品級 PE 膜或無紡布，直接接觸餐品，需符合食品安全標(biāo)準(zhǔn)，PE 膜光滑易清潔，無紡布透氣性略好適合熱食散發(fā)少量水汽，避免袋內(nèi)凝結(jié)水珠影響餐品口感。

　　The layered combination of insulation materials is the basis of the design of insulation packaging bags, which achieves temperature maintenance by blocking the heat transfer path. The outer layer is often made of Oxford cloth or nylon cloth, which has high density and strong wear resistance, and can resist friction and slight impact during distribution. The surface is treated with a waterproof coating to prevent rainwater from penetrating and affecting the inner insulation material. The middle insulation layer is the core, and common materials include pearl cotton, aluminum foil composite bubble film, etc. Pearl cotton has a lightweight and elastic texture, and numerous independent bubbles inside can effectively block air convection. At the same time, it has a certain buffering effect and is suitable for holding soup and other easily spilled food; Aluminum foil composite bubble film blocks thermal radiation through the reflection effect of aluminum foil, reduces air conduction in the bubble layer, and has a better insulation effect than pearl cotton. It is commonly used in scenarios that require long-term insulation. The inner layer is usually made of food grade PE film or non-woven fabric, which comes into direct contact with the food and meets food safety standards. The PE film is smooth and easy to clean, and the non-woven fabric has slightly better breathability, suitable for hot food to emit a small amount of water vapor and avoid condensation of water droplets inside the bag affecting the taste of the food.

　　結(jié)構(gòu)設(shè)計(jì)需強(qiáng)化密封性，減少內(nèi)外空氣流通帶來的熱量損失。袋口采用雙重密封方式，基礎(chǔ)設(shè)計(jì)是魔術(shù)貼封口，寬大的魔術(shù)貼確保貼合緊密，部分高端保溫袋在此基礎(chǔ)上增加拉鏈封口，拉鏈閉合后能進(jìn)一步壓縮袋口縫隙，減少熱量流失。袋體形狀以立體方形為主，內(nèi)部空間規(guī)整，避免餐盒晃動(dòng)導(dǎo)致的縫隙增大，側(cè)面采用立體風(fēng)琴褶設(shè)計(jì)，可根據(jù)餐品數(shù)量調(diào)整容量，裝滿時(shí)褶皺展開貼合餐盒，減少內(nèi)部空隙。底部設(shè)計(jì)為加厚承重結(jié)構(gòu)，多層布料復(fù)合并加硬紙板支撐，能承受一定重量不變形，避免底部下垂導(dǎo)致袋口密封失效，同時(shí)防止高溫餐盒直接接觸桌面燙壞包裝。

　　The structural design needs to strengthen sealing and reduce heat loss caused by internal and external air circulation. The bag mouth adopts a double sealing method, with a basic design of Velcro sealing. The wide Velcro ensures a tight fit, and some high-end insulation bags add zipper sealing on this basis. After the zipper is closed, it can further compress the gap of the bag mouth and reduce heat loss. The shape of the bag is mainly three-dimensional square, with a regular internal space to avoid the increase of gaps caused by the shaking of the food box. The side adopts a three-dimensional accordion fold design, which can adjust the capacity according to the number of dishes. When filled, the folds unfold and fit the food box, reducing internal gaps. The bottom is designed as a thickened load-bearing structure, with multiple layers of fabric composite and hard cardboard support, which can withstand a certain weight without deformation, avoiding the bottom sagging and causing the bag seal to fail. At the same time, it prevents the high-temperature lunch box from directly contacting the desktop and damaging the packaging.

　　功能分區(qū)設(shè)計(jì)提升保溫針對性，滿足不同餐品的溫度需求。多格分層設(shè)計(jì)在大型保溫袋中常見，通過可拆卸隔板將內(nèi)部劃分為多個(gè)獨(dú)立空間，可同時(shí)放置熱食與冷食，避免溫度相互影響 —— 熱區(qū)采用厚保溫層，冷區(qū)在保溫層外增加反光鋁箔，強(qiáng)化各自的溫度保持效果。側(cè)邊口袋用于放置冰袋或暖寶寶，需要長時(shí)間保溫時(shí)，將冰袋放入冷食區(qū)旁的專用口袋，通過低溫傳導(dǎo)維持冷區(qū)溫度；熱食配送可在袋內(nèi)角落放置暖寶寶，延長保溫時(shí)間。部分保溫袋設(shè)計(jì)有透氣閥，當(dāng)熱食溫度過高產(chǎn)生蒸汽時(shí)，可手動(dòng)打開微透氣孔釋放壓力，防止袋內(nèi)氣壓過大導(dǎo)致封口崩開，同時(shí)避免完全密封產(chǎn)生的冷凝水積聚。

　　Functional zoning design enhances insulation targeting and meets the temperature requirements of different dishes. Multi grid layered design is common in large insulation bags, which divides the interior into multiple independent spaces through detachable partitions, allowing for the simultaneous placement of hot and cold food to avoid temperature interference. The hot zone uses a thick insulation layer, while the cold zone adds reflective aluminum foil outside the insulation layer to enhance their respective temperature retention effects. Side pockets are used to store ice packs or warm babies. When prolonged insulation is required, place the ice pack in a dedicated pocket next to the cold food area to maintain the temperature of the cold area through low-temperature conduction; Hot food delivery can be placed in the corner of the bag to warm the baby and extend the insulation time. Some insulation bags are designed with breathable valves. When the hot food temperature is too high and steam is generated, the micro breathable holes can be manually opened to release pressure, preventing the seal from breaking due to excessive air pressure inside the bag and avoiding the accumulation of condensation water caused by complete sealing.

　　人體工學(xué)與使用便利性設(shè)計(jì)讓保溫袋更適配配送場景。提手采用加寬織帶，并做加厚處理，分散手部壓力，避免長時(shí)間提握造成不適，部分提手可調(diào)節(jié)長度，兼顧手提與肩背兩種方式，方便配送員騎行時(shí)攜帶。袋身側(cè)面或背面設(shè)計(jì)有透明卡片袋，可放置訂單信息，避免配送過程中反復(fù)翻找影響效率。折疊收納功能也很重要，空袋時(shí)可沿折痕折疊成扁平狀，節(jié)省配送箱內(nèi)空間，部分產(chǎn)品采用可壓縮設(shè)計(jì)，通過魔術(shù)貼將折疊后的袋體固定，方便存放。

　　Ergonomic and user-friendly design makes the insulated bag more suitable for delivery scenarios. The handle adopts widened webbing and thickened treatment to disperse hand pressure and avoid discomfort caused by prolonged grip. Some handles can be adjusted in length, taking into account both handheld and shoulder back modes, making it convenient for delivery personnel to carry while riding. The side or back of the bag is designed with a transparent card bag, which can hold order information to avoid repeatedly searching and affecting efficiency during the delivery process. The folding and storage function is also very important. When the bag is empty, it can be folded into a flat shape along the crease to save space inside the distribution box. Some products adopt a compressible design, and the folded bag body is fixed by Velcro for convenient storage.

　　保溫型外賣打包袋的設(shè)計(jì)是材料科學(xué)與實(shí)用需求的結(jié)合，從外層防護(hù)到內(nèi)層接觸，從整體結(jié)構(gòu)到細(xì)節(jié)處理，每一處設(shè)計(jì)都服務(wù)于 “溫度保持” 核心目標(biāo)。其設(shè)計(jì)需根據(jù)配送時(shí)長、餐品類型、配送環(huán)境進(jìn)行調(diào)整。隨著消費(fèi)者對餐品品質(zhì)要求的提升，保溫型打包袋的設(shè)計(jì)正朝著輕量化、多功能化方向發(fā)展，在保證保溫效果的同時(shí)，進(jìn)一步降低配送負(fù)擔(dān)，成為連接商家與消費(fèi)者的重要橋梁。

　　The design of insulated takeaway packaging bags is a combination of material science and practical needs. From outer protection to inner contact, from overall structure to detail treatment, every design serves the core goal of "temperature maintenance". Its design needs to be adjusted according to the delivery time, type of food, and delivery environment. With the increasing demand of consumers for food quality, the design of insulated packaging bags is developing towards lightweight and multifunctional direction. While ensuring insulation effect, it further reduces the delivery burden and becomes an important bridge connecting businesses and consumers.
