Waterproof Brown Color 31inch / 35inch Anti Oil Recycled Cardboard Paper

Food Packaging Kraft Paper, Yellow Kraft Paper, White Kraft Paper, Anti-Oil Immersion, Moisture-proof Kraft For Packing

Food grade Kraft paper for food packaging.

In Kraft paper products there is a special needs of Kraft paper, that is food packaging Kraft paper, benefiting from the national attention to food safety, as food packaging materials the food packaging Kraft paper market demand continues to be increased, products continue to standardize, food packaging Kraft paper is currently characterized by almost all the use of full wood pulp production. As use of recycled pulp and can reach the food packaging Kraft level of the product has not yet appeared on the top of the market.

Food grade Kraft paper with more environmentally friendly properties than plastic and other packaging. Its performance is also very superior, moisture-proof waterproof, anti-oil immersion, low-temperature freezing, can delay shelf life and other substances. You can buy anti-oil Kraft bags for food packaging from our company. The cost of food-grade Kraft paper is relatively lower when the barrier effect is the same compared to packaging materials such as plastics and glass.

Food packaging Kraft paper currently mainly has yellow Kraft paper and white Kraft paper two occupy the main market share, the current market of such products are mainly concentrated in the quality of standards and testing reports are not complete features, but the use of food Kraft paper customers are mostly to pick up foreign orders users, and such customers often need food-grade reports more complete, So at present, the domestic food packaging Kraft paper production enterprises need to improve their own depth in the detection report, now different countries will require Kraft paper manufacturers to provide different food grade testing reports, such as the export of food-grade printing and packaging products in the United States will ask for FDA reports, And as a junior SGS report has been unable to meet the current market demand.
An important test index of food grade white Kraft paper properties are the content of fluorescent agent, the content of which is too high will be harmful to human health. Because without adding brightener, the whiteness of white Kraft paper is very difficult to achieve high whiteness. In order to achieve this whiteness, many Kraft paper manufacturers will add a large number of phosphor as a brightener in production. But phosphors are harmful to the human body, and long-term exposure can be a cancer-causing risk. Therefore, in the food packaging industry is absolutely forbidden to use the addition of phosphor white Kraft paper.

So what simple ways do we have in our daily lives to quickly detect whether the fluorescent content of white Kraft paper is exceeding the standard, and we can use these simple methods.
1. Use a currency detector to detect. This is a relatively quick and easy way, is that we will UV function of the currency detector directly to white Kraft paper irradiation, and then slow movement, if there is a clear fluorescence phenomenon, it shows that the white Kraft paper product fluorescent content is seriously exceeded, cannot be used in food packaging.
2. Sunlight irradiation method, the method of low accuracy, because the sun itself contains ultraviolet light, if you can see fluorescent substances, but also that the white Kraft paper fluorescent agent exceeded the standard. This method is said to be less accurate because if we can see fluorescent substances in the sun, it shows that the white Kraft paper product fluorescent agent has been seriously exceeded. In fact, sometimes fluorescent agent content exceeding a certain range we can not see in the sun, so it is generally not recommended to use this method.
3. Naked eye observation method. The so-called naked eye observation method is that we directly look at the whiteness of white Kraft paper. Generally speaking, the whiteness of food grade white Kraft paper is relatively low, even some yellowish. If the white Kraft paper on your hand is as white as the A4 copy sheet, it goes without saying that this white Kraft paper can be clearly judged to be non-food grade.
