在如今的餐饮行业竞争中，店铺餐品的竞争已经远远不止餐品本身那么简单，餐品的包装设计也同样重要，且对于吸引潜在客户群体而来，餐品的包装设计会越来越重要。

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.

当然，在我们关注产品设计美观与否的同时，也得把食品包装的安全问题放在举足轻重的位置，特别是那些直接接触食品的包装材料。今天我们就来谈谈关于食品级包装用纸的那些小知识，去了解一下何谓真正的食品级包装用纸。

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?

柔印是一种直接印刷方式，使用具有弹性的凸起的图像印版，能将液体或脂状油墨转移到几乎所有类型的材料上，属于轻压印刷。柔印比较独特灵活，且经济节约，有利环保，符合食品包装印刷品卫生标准，是食品包装用纸的主要印刷方式。

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.

而水性油墨是柔印机的专用墨，由于它性能稳定、色彩鲜艳、环保无污染、安全不易燃等，特别适用于对卫生要求严格的食品类、医药类等包装用纸的印刷。

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.

02什么是瓦楞纸板？有什么优点？

What is corrugated cardboard? What are the advantages?

瓦楞纸板，一种厚而粗糙的纸张，波形瓦楞状，有弹性。因采用瓦楞纸板制成的包装容器对美化和保护内装商品有其独特的性能和优点，成为迄今为止发展迅速、且经久不衰的食品包装用纸的主要选择之一。

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.

瓦楞纸板是由面纸、里纸、芯纸和加工成波形瓦楞的瓦楞纸通过粘合而成。根据商品包装的需求，可加工成单层、3层、5层、7层、11层等瓦楞纸板。

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.

单层瓦楞纸板一般用作商品包装的贴衬保护层、或制作轻便的垫板等，以避免商品在储运过程中发生震动或冲撞。

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层和5层瓦楞纸板在制作瓦楞纸箱中经常用的；而7层或11层瓦楞纸板主要为机电、烤烟、家俱、摩托车、大型家电等制作包装箱。

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.

03什么是牛皮纸？为什么牛皮纸包装盒更耐用？

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

牛皮纸是用未漂针叶木硫酸盐浆生产的纸。强度很高，通常呈黄褐色。半漂或全漂的牛皮纸浆呈淡褐色、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.

针叶树的木材纤维是制作牛皮纸的主要原料，而这种树的纤维比较长，为了尽可能不损伤纤维的韧度，通常是烧碱和硫化碱化学药品的方式进行处理，纤维与纤维之间是紧紧相依的，这样就能很好地保持木材纤维本身的韧度和牢固度，因此生产出的牛皮纸张的强度就远高于普通纸张，也就更结实耐用了。

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.

牛皮纸包装盒因其独特的色彩和环保属性、以及强大的物理性能，在包装行业中大受追捧，且发展趋势也很猛。

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.

04什么是荧光剂？如何检测食品包装用纸的荧光反应？

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

荧光剂是一种荧光染料，是一种复杂的有机化合物。它能激发入射光线产生荧光，使肉眼看到的物质显得更白、更亮、更鲜艳。而造纸行业比较多见的是造纸用液体增白剂，因为它可以提高纸制品在日光下的整体美观度。

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.

而对于食品包装用纸来说，荧光剂的存在是不符合食品安全需求的。而且含有荧光剂的食品包装用纸在使用过程中可能会迁移到食物中，从而被人体吸收，不易分解，不断累积在人体后会危害人体健康。

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.

而检测我们的食品包装用纸是否含有明显的荧光物质，可以选择紫外线灯。只需要用手持式双波长紫外线灯照射到包装用纸上，如果被照射的纸张发生明显荧光反应，证明其含有荧光物质。

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为什么食品级包装用纸一定要完全采用原生木浆为原料？

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

当食品包装用纸与食品直接接触时，食品安全问题尤为重要。而完全采用原生木浆的食品包装用纸不存在受污染的风险，可安全接触食品，不会将有害成分转移到食品上。

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.

而且原生木浆纤维韧性佳、密度高、强度好，加工性能也更好，在加工生产的过程中无需添加特殊成分来改善纸张的外观、颜色、性能等。不但提高了资源的使用效率，而且纸张触感好、自然本色（色泽均匀、无霉斑、无黑点等）、印刷效果好、不会产生异味。

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食品级包装用纸所需的原生木浆（原纸）必须达到什么标准？

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

必须符合新版GB 4806.8-2016标准要求（于2017年4月19日启用）。特别提示：GB 4806.8-2016《国家食品安全标准 食品接触用纸和纸板材料及制品》已取代GB 11680-1989《食品包装用原纸卫生卫生标准》。

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".

其中明确规定了食品接触用原纸必须达到的理化指标，包含铅砷指标、甲醛和荧光性物质残留指标、微生物限量和总迁移量、高锰酸钾消耗量、重金属等迁移性指标。

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.
