在如今的餐飲行業(yè)競爭中，店鋪餐品的競爭已經(jīng)遠(yuǎn)遠(yuǎn)不止餐品本身那么簡單，餐品的包裝設(shè)計(jì)也同樣重要，且對于吸引潛在客戶群體而來，餐品的包裝設(shè)計(jì)會(huì)越來越重要。

In today's competition in the catering industry, the competition for restaurant food products is far more than just the food itself. The packaging design of food products is also equally important, and for attracting potential customer groups, the packaging design of food products will become increasingly important.

當(dāng)然，在我們關(guān)注產(chǎn)品設(shè)計(jì)美觀與否的同時(shí)，也得把食品包裝的安全問題放在舉足輕重的位置，特別是那些直接接觸食品的包裝材料。今天我們就來談?wù)勱P(guān)于食品級包裝用紙的那些小知識(shí)，去了解一下何謂真正的食品級包裝用紙。

Of course, while we focus on whether the product design is aesthetically pleasing, we also need to prioritize the safety of food packaging, especially for packaging materials that come into direct contact with food. Today, let's talk about some small knowledge about food grade packaging paper and understand what true food grade packaging paper is.

01什么是柔印？什么是水性油墨？

What is flexographic printing? What is water-based ink?

柔印是一種直接印刷方式，使用具有彈性的凸起的圖像印版，能將液體或脂狀油墨轉(zhuǎn)移到幾乎所有類型的材料上，屬于輕壓印刷。柔印比較獨(dú)特靈活，且經(jīng)濟(jì)節(jié)約，有利環(huán)保，符合食品包裝印刷品衛(wèi)生標(biāo)準(zhǔn)，是食品包裝用紙的主要印刷方式。

Flexographic printing is a direct printing method that uses elastic raised image plates to transfer liquid or greasy ink to almost all types of materials, belonging to light pressure printing. Flexographic printing is unique, flexible, cost-effective, environmentally friendly, and meets the hygiene standards for food packaging printing. It is the main printing method for food packaging paper.

而水性油墨是柔印機(jī)的專用墨，由于它性能穩(wěn)定、色彩鮮艷、環(huán)保無污染、安全不易燃等，特別適用于對衛(wèi)生要求嚴(yán)格的食品類、醫(yī)藥類等包裝用紙的印刷。

And water-based ink is a specialized ink for flexographic printing machines. Due to its stable performance, bright colors, environmental friendliness, non pollution, safety, and non flammability, it is particularly suitable for printing packaging paper such as food and medicine that have strict hygiene requirements.

02什么是瓦楞紙板？有什么優(yōu)點(diǎn)？

What is corrugated cardboard? What are the advantages?

瓦楞紙板，一種厚而粗糙的紙張，波形瓦楞狀，有彈性。因采用瓦楞紙板制成的包裝容器對美化和保護(hù)內(nèi)裝商品有其獨(dú)特的性能和優(yōu)點(diǎn)，成為迄今為止發(fā)展迅速、且經(jīng)久不衰的食品包裝用紙的主要選擇之一。

Corrugated cardboard, a thick and rough paper with a wavy corrugated shape and elasticity. Due to the unique performance and advantages of packaging containers made of corrugated cardboard in beautifying and protecting the contents of goods, they have become one of the main choices for food packaging paper that has developed rapidly and has been enduring for a long time.

瓦楞紙板是由面紙、里紙、芯紙和加工成波形瓦楞的瓦楞紙通過粘合而成。根據(jù)商品包裝的需求，可加工成單層、3層、5層、7層、11層等瓦楞紙板。

Corrugated cardboard is made by bonding surface paper, inner paper, core paper, and corrugated paper processed into corrugated waves. According to the packaging requirements of the product, it can be processed into single-layer, 3-layer, 5-layer, 7-layer, 11 layer corrugated cardboard, etc.

單層瓦楞紙板一般用作商品包裝的貼襯保護(hù)層、或制作輕便的墊板等，以避免商品在儲(chǔ)運(yùn)過程中發(fā)生震動(dòng)或沖撞。

Single layer corrugated cardboard is generally used as a protective layer for product packaging or as a lightweight pad to avoid vibration or collision during storage and transportation.

3層和5層瓦楞紙板在制作瓦楞紙箱中經(jīng)常用的；而7層或11層瓦楞紙板主要為機(jī)電、烤煙、家俱、摩托車、大型家電等制作包裝箱。

3-layer and 5-layer corrugated cardboard are commonly used in the production of corrugated cardboard boxes; The 7-layer or 11-layer corrugated cardboard is mainly used to produce packaging boxes for electromechanical, tobacco, furniture, motorcycles, large household appliances, etc.

03什么是牛皮紙？為什么牛皮紙包裝盒更耐用？

03 What is kraft paper? Why are kraft paper packaging boxes more durable?

牛皮紙是用未漂針葉木硫酸鹽漿生產(chǎn)的紙。強(qiáng)度很高，通常呈黃褐色。半漂或全漂的牛皮紙漿呈淡褐色、奶油色或白色。

Kraft paper is produced from unbleached coniferous wood sulfate pulp. It has high intensity and is usually yellow brown in color. Half bleached or fully bleached cowhide pulp appears light brown, cream colored, or white.

針葉樹的木材纖維是制作牛皮紙的主要原料，而這種樹的纖維比較長，為了盡可能不損傷纖維的韌度，通常是燒堿和硫化堿化學(xué)藥品的方式進(jìn)行處理，纖維與纖維之間是緊緊相依的，這樣就能很好地保持木材纖維本身的韌度和牢固度，因此生產(chǎn)出的牛皮紙張的強(qiáng)度就遠(yuǎn)高于普通紙張，也就更結(jié)實(shí)耐用了。

The wood fibers of coniferous trees are the main raw material for making kraft paper, and the fibers of this tree are relatively long. In order to minimize damage to the toughness of the fibers, they are usually treated with caustic soda and sulfurized alkali chemicals. The fibers are tightly dependent on each other, which can maintain the toughness and firmness of the wood fibers themselves. Therefore, the strength of the produced kraft paper is much higher than that of ordinary paper, It is also more sturdy and durable.

牛皮紙包裝盒因其獨(dú)特的色彩和環(huán)保屬性、以及強(qiáng)大的物理性能，在包裝行業(yè)中大受追捧，且發(fā)展趨勢也很猛。

Kraft paper packaging boxes are highly sought after in the packaging industry due to their unique colors, environmental attributes, and strong physical properties, and their development trend is also fierce.

04什么是熒光劑？如何檢測食品包裝用紙的熒光反應(yīng)？

What is a fluorescent agent? How to detect the fluorescence reaction of food packaging paper?

熒光劑是一種熒光染料，是一種復(fù)雜的有機(jī)化合物。它能激發(fā)入射光線產(chǎn)生熒光，使肉眼看到的物質(zhì)顯得更白、更亮、更鮮艷。而造紙行業(yè)比較多見的是造紙用液體增白劑，因?yàn)樗梢蕴岣呒堉破吩谌展庀碌恼w美觀度。

Fluorescent agent is a fluorescent dye and a complex organic compound. It can stimulate incident light to produce fluorescence, making substances visible to the naked eye appear whiter, brighter, and more vibrant. In the paper industry, liquid whitening agents are commonly used in papermaking because they can improve the overall aesthetics of paper products under sunlight.

而對于食品包裝用紙來說，熒光劑的存在是不符合食品安全需求的。而且含有熒光劑的食品包裝用紙?jiān)谑褂眠^程中可能會(huì)遷移到食物中，從而被人體吸收，不易分解，不斷累積在人體后會(huì)危害人體健康。

For food packaging paper, the presence of fluorescent agents does not meet food safety requirements. Moreover, food packaging paper containing fluorescent agents may migrate into the food during use, which can be absorbed by the human body and not easily decomposed. Continuously accumulating in the human body can pose a threat to human health.

而檢測我們的食品包裝用紙是否含有明顯的熒光物質(zhì)，可以選擇紫外線燈。只需要用手持式雙波長紫外線燈照射到包裝用紙上，如果被照射的紙張發(fā)生明顯熒光反應(yīng)，證明其含有熒光物質(zhì)。

And to test whether our food packaging paper contains obvious fluorescent substances, we can choose ultraviolet lamps. Just use a handheld dual wavelength ultraviolet lamp to irradiate the packaging paper. If the irradiated paper undergoes a significant fluorescence reaction, it indicates that it contains fluorescent substances.

05為什么食品級包裝用紙一定要完全采用原生木漿為原料？

Why does food grade packaging paper always use native wood pulp as the raw material?

當(dāng)食品包裝用紙與食品直接接觸時(shí)，食品安全問題尤為重要。而完全采用原生木漿的食品包裝用紙不存在受污染的風(fēng)險(xiǎn)，可安全接觸食品，不會(huì)將有害成分轉(zhuǎn)移到食品上。

When food packaging paper comes into direct contact with food, food safety issues are particularly important. The food packaging paper that completely uses native wood pulp does not have the risk of contamination, can safely come into contact with food, and will not transfer harmful ingredients to the food.

而且原生木漿纖維韌性佳、密度高、強(qiáng)度好，加工性能也更好，在加工生產(chǎn)的過程中無需添加特殊成分來改善紙張的外觀、顏色、性能等。不但提高了資源的使用效率，而且紙張觸感好、自然本色（色澤均勻、無霉斑、無黑點(diǎn)等）、印刷效果好、不會(huì)產(chǎn)生異味。

Moreover, the native wood pulp fibers have good toughness, high density, good strength, and better processing performance. There is no need to add special ingredients to improve the appearance, color, and performance of the paper during the processing and production process. Not only does it improve the efficiency of resource utilization, but the paper also has a good texture, natural color (uniform color, no mold, no black spots, etc.), good printing effect, and no odor.

06食品級包裝用紙所需的原生木漿（原紙）必須達(dá)到什么標(biāo)準(zhǔn)？

What standards must be met for the raw wood pulp (base paper) required for 06 food grade packaging paper?

必須符合新版GB 4806.8-2016標(biāo)準(zhǔn)要求（于2017年4月19日啟用）。特別提示：GB 4806.8-2016《國家食品安全標(biāo)準(zhǔn) 食品接觸用紙和紙板材料及制品》已取代GB 11680-1989《食品包裝用原紙衛(wèi)生衛(wèi)生標(biāo)準(zhǔn)》。

Must comply with the requirements of the new GB 4806.8-2016 standard (put into use on April 19, 2017). Special reminder: GB 4806.8-2016 "National Food Safety Standards - Materials and Products of Paper and Paperboard in Contact with Food" has replaced GB 11680-1989 "Hygienic Standards for Raw Paper for Food Packaging".

其中明確規(guī)定了食品接觸用原紙必須達(dá)到的理化指標(biāo)，包含鉛砷指標(biāo)、甲醛和熒光性物質(zhì)殘留指標(biāo)、微生物限量和總遷移量、高錳酸鉀消耗量、重金屬等遷移性指標(biāo)。

It clearly stipulates the physical and chemical indicators that must be met for food contact paper, including lead and arsenic indicators, residual indicators of formaldehyde and fluorescent substances, microbial limits and total migration, potassium permanganate consumption, and migration indicators of heavy metals.
