Recently, the Beijing News reporter from Beijing to collect 10 large and small restaurant napkin which provided expert testing found that only two restaurants provide napkins completely non-fluorescent.
Samples provided to reporters, Secretary-General of the International Food Packaging Association Dong Jinshi, three experiments were done, find some restaurant napkin containing a certain area of the fluorescent agent, and some napkins color black combustion, less fiber content, which may be doped with impurities The 'paper' made of these restaurants both well-known restaurants and fast food outlets, but also ordinary small restaurants, including McDonald's, KFC, Yoshinoya, Chongqing and other rural people.
Cost is a major factor manufacturers use waste paper. Dong Jinshi introduction, such as the use of paper napkins made, the price of 1,500 yuan per ton, with pure straw is 2500 yuan per ton, while the pure wood pulp manufacturing, prices have nearly 5,000 yuan. After producers manufactured with paper napkins, usually adding talc, calcium carbonate, and some will come with fluorescent whitening agents, and enough weight so that looks good sell.
City of Industry, tips that can make paper white fluorescent brightener, its current understanding of the harm is not uniform, standard specifies the napkin should not have to migrate fluorescent whitening agents, fluorescent agents to prevent the transfer to humans.
Dong Jinshi reminded that focus on a napkin marked buy depends on whether the packaging is '100% virgin wood pulp.' In restaurants, Taebaek or too dark, smell taste, shaking up the hair loss, a look to the light 'leaks' more napkins, try not to use all the best.
Time and place: December 16, International Food Packaging Association
Experimental sample: Reporters randomly collected from 10 restaurants in napkins
[Experiment 1]
Two kinds of napkins completely non-fluorescent
Purpose: examine whether there is a fluorescent brightener on a napkin.
Experimental procedure: testers put under the napkin professional UV irradiation analyzer to see if the display bright blue napkins .10 species, only the new spicy Kwok Shui Road, Yonghe City stores and large stores of two napkins fluorescent display completely McDonald KFC napkin sporadic fluorescent spots. fluorescent largest napkins from the abundance of the road, 'lead to the snack bar.'
[Expert Interpretation] Dong Jinshi pointed out that part of fluorescent spots scattered on a napkin, the general nature of raw materials may be brought in, consumers need not panic. As larger fluorescence, which is artificially added napkins or fluorescent agent, or the use of waste paper production, some studies show that the fluorescent agent may cause leukemia.
[Experiment 2]
One kind of burned black napkin
Purpose: to verify whether the dopant impurity napkins.
Experiment: the experimenter sampling 10 kinds of napkins were to ignite, burn completely and check the state of most of the napkin color ash ashes pale flocculent, but lead to the snack bar napkin, its color but black ashes like. black lump, burning taste.
[Expert Interpretation] Dong Lion said, according to the provisions of doping or the use of paper napkins can not be manufactured, the color black napkin after burning description is not pure or pure straw pulp production, paper inside the inorganic minerals such as talc, carbonates Adding more calcium Such napkins are not strong, easy dregs hair loss, if you add an excess of talc, may contain heavy metals, dip the body may cause skin allergy.
[Experiment 3]
Poor quality fiber napkins 3
Purpose: View napkins strength is good or bad.
Experiment: the 10 kinds of water to wet napkin, fully wet, and then try to get up and put a napkin full of good quality paper napkin soaked still intact even after tests found picked up, people Szechuan Chongqing Rural Street store. Fung Dumpling House Northeast pipeline, napkins snack Fengguan lead to the use of these three restaurants, has just been broken soaked horrendous and can not retake it.
[Expert Interpretation] Dong Jinshi pointed out a napkin carry on the break, described in the paper fiber content is relatively small, relatively poor fiber quality, does not rule out the possibility of using renewable waste paper.
