包裝的主要作用

　　The main function of packaging

　　其一是保護產品；其二是美化和宣傳產品。包裝設計的基本任務是科學地、經濟地完成產品包裝的造型、結構和裝潢設計。它運用美學原則，通過形態、色彩等因素的變化，將具有包裝功能和外觀美的包裝容器造型，以視覺形式表現出來。包裝容器必須能可靠地保護產品，必須有優良的外觀，還需具有相適應的經濟性等。

　　One is to protect the product; The second is to beautify and promote the product. The basic task of packaging design is to scientifically and economically complete the shape, structure, and decoration design of product packaging.

The packaging container must be able to reliably protect the product, have a good appearance, and also have suitable economy.

　　一、塑料餐具01選購提示

　　1、 Plastic tableware 01 purchase tips

　　1.材質標識要看清：查看產品說明，優先選擇標有 “食品接觸用” 字樣、材質為聚丙烯（PP）或聚乙烯（PE）等，這類材質安全性較高。例如，常見的 PP 材質塑料飯盒，在正常使用溫度下較為穩定。2.外觀檢查不可少：挑選時，確保餐具表面光滑，無毛刺、氣泡、雜質或異味。若餐具邊緣粗糙，可能會劃傷嘴巴；有刺鼻氣味，可能存在有害物質揮發。3.購買渠道要正規：建議前往正規超市、商場或信譽良好的電商平臺購買，這些渠道的產品質量更有保障，可減少買到三無產品的風險。

　　1. Material identification should be clear: Check the product description and prioritize selecting materials labeled "for food contact" such as polypropylene (PP) or polyethylene (PE), which have higher safety. For example, common PP plastic lunch boxes are relatively stable at normal operating temperatures. 2. Appearance inspection is essential: When selecting, ensure that the surface of the tableware is smooth, without burrs, bubbles, impurities, or odors. If the edges of the tableware are rough, it may scratch the mouth; There is a pungent odor and there may be harmful substances evaporating. 3. Regular purchasing channels: It is recommended to go to regular supermarkets, shopping malls, or reputable e-commerce platforms to purchase. The quality of products from these channels is more guaranteed, which can reduce the risk of buying three no products.

　　1.避免高溫加熱：絕不能將普通塑料餐具放入微波爐、烤箱等高溫設備中加熱，高溫易使塑料變形，還可能導致其中的有害物質遷移到食物中。如需微波加熱，務必使用標有 “可微波” 字樣的塑料餐具。2.及時清洗防殘留：使用后盡快清洗塑料餐具，尤其是盛裝過油膩、含糖食物后，避免食物殘渣殘留滋生細菌。清洗時，用溫和的洗潔精和清水沖洗，不要使用鋼絲球等尖銳工具，以免刮傷餐具表面。3.定期更換保安全：若塑料餐具出現明顯磨損、變色、變形或有裂紋，應及時更換。長期使用老化的塑料餐具，有害物質滲出風險增加。

　　1. Avoid high temperature heating: Ordinary plastic tableware should never be placed in high-temperature equipment such as microwave ovens or ovens for heating. High temperatures can easily deform plastics and may also cause harmful substances to migrate into food. If microwave heating is required, be sure to use plastic tableware marked with the words "microwave ready". 2. Timely cleaning to prevent residue: Clean plastic tableware as soon as possible after use, especially after containing greasy or sugary food, to avoid the growth of bacteria caused by food residue. When cleaning, rinse with mild detergent and clean water. Do not use sharp tools such as steel wool to avoid scratching the surface of the tableware. 3. Regular replacement for safety: If plastic tableware shows obvious wear, discoloration, deformation, or cracks, it should be replaced in a timely manner. Long term use of aged plastic tableware increases the risk of harmful substances seeping out.

　　二、保鮮膜01選購提示

　　2、 Tips for purchasing cling film 01

　　1.材質特性需了解：保鮮膜常見材質有聚乙烯（PE）、聚氯乙烯（PVC）和聚偏二氯乙烯（PVDC）。PE 保鮮膜安全系數高，可用于日常食品包裝；PVC 保鮮膜因含有塑化劑，不適合包裹油脂類食物；PVDC 保鮮膜成本高，多用于熟食包裝。購買時看清材質說明。2.外觀質量嚴把關：選擇表面平整、無氣泡、無雜質、無異味的保鮮膜。輕輕拉扯，具有良好拉伸性、不易破裂的產品質量更佳。3.正規產品更放心：從正規渠道購買，確保產品包裝完好，有清晰的品牌、生產日期、保質期及使用說明等標識。

　　1. Material characteristics need to be understood: Common materials for cling film include polyethylene (PE), polyvinyl chloride (PVC), and polyvinylidene chloride (PVDC). PE cling film has a high safety factor and can be used for daily food packaging; PVC cling film is not suitable for wrapping oily food due to the presence of plasticizers; PVDC cling film has a high cost and is often used for packaging cooked food. Please read the material instructions carefully when purchasing. 2. Strict quality control of appearance: Choose plastic wrap with a smooth surface, no bubbles, no impurities, and no odors. Gently pulling, products with good stretchability and less prone to breakage have better quality. 3. Regular products are more reassuring: Purchase from regular channels to ensure that the product packaging is intact, with clear brand, production date, shelf life, and instructions for use.

　　02 Usage tips

　　1.正確包裹防交叉：包裹食物時，盡量排出空氣，以延長保鮮時間。注意生熟食品要分開包裹，防止交叉污染。2.注意使用溫度：普通保鮮膜不耐高溫，不能直接在微波爐中加熱。若需微波加熱，應使用專門的可微波保鮮膜，并遵循產品說明操作。3.避免長期接觸油脂：油脂會加速保鮮膜中有害物質的遷移，因此盡量不要用保鮮膜長時間包裹油炸食品、肥肉等高油脂食物。

　　1. Proper packaging to prevent cross wrapping: When wrapping food, try to exhaust air as much as possible to extend the shelf life. Please package raw and cooked food separately to prevent cross contamination. 2. Pay attention to the usage temperature: Ordinary cling film is not resistant to high temperatures and cannot be directly heated in a microwave oven. If microwave heating is required, specialized microwaveable cling film should be used and the product instructions should be followed. 3. Avoid long-term exposure to oil: Oil can accelerate the migration of harmful substances in cling film, so try not to wrap high-fat foods such as fried foods and fatty meat with cling film for a long time.

　　三、食品包裝袋01選購提示

　　3、 Food Packaging Bag 01 Selection Tips

　　1.符合標準是關鍵：購買時查看包裝袋是否標注 “食品用” 字樣，以及是否符合相應的食品安全國家標準，如 GB 4806.7-2023等。2.外觀細節細觀察：優質食品包裝袋應質地均勻、無異味、無破洞、無明顯褶皺。顏色過于鮮艷或有刺鼻氣味的包裝袋，可能存在染料或添加劑超標問題。3.按需選擇不同類型：根據包裝需求選擇，如冷凍食品需選用耐寒、耐低溫的包裝袋；真空包裝食品要選擇密封性好的袋子。

　　1. Compliance with standards is key: When purchasing, check whether the packaging bag is labeled with the words "for food use" and whether it meets the corresponding national food safety standards, such as GB 4806.7-2023. 2. Careful observation of appearance details: High quality food packaging bags should have a uniform texture, no odor, no holes, and no obvious wrinkles. Packaging bags with overly bright colors or pungent odors may have issues with excessive dyes or additives. 3. Choose different types as needed: Choose according to packaging requirements, such as using cold resistant and low-temperature resistant packaging bags for frozen foods; Vacuum packaged food should choose bags with good sealing properties.

　　1.正確存放保質量：未使用的食品包裝袋應存放在干燥、陰涼處，避免陽光直射和高溫環境，防止老化變質。2.避免重復使用：一次性食品包裝袋在使用后，即使外觀完好，也不建議重復使用，以防細菌滋生和有害物質滲出。3.注意包裝食品特性：對于容易產生氣體的食品，如發酵食品，不要將包裝袋密封過緊，以防脹袋破裂。

　　1. Proper storage to ensure quality: Unused food packaging bags should be stored in a dry, cool place, away from direct sunlight and high temperature environments, to prevent aging and deterioration. 2. Avoid reuse: Disposable food packaging bags, even if they look good after use, are not recommended for reuse to prevent bacterial growth and harmful substances from seeping out. 3. Pay attention to the characteristics of packaged food: For foods that are prone to gas production, such as fermented foods, do not seal the packaging bag too tightly to prevent the bag from bursting.
