The features of pearlized paper

Pearlized paper has single-sided and double-sided parts, which can be produced according to different requirements such as demand, color, quantitative (gram weight), texture and size.

Pearlescent paper and synthetic paper are a kind of new packaging and printing materials. They are also an environmentally friendly material. They have both paper characteristics and plastic advantages. They are light in weight, waterproof, tear-resistant, corrosion-resistant and wear-resistant. Advertising, packaging, printing, adhesives, barcodes, labels, handbags, tags, books, maps, etc. Pearl crepe paper has very nice fancy surface compare to other color paper. Our pearlized crepe paper mainly used in arts and craftwork, and widely used in gift wrapping,paper flowers, Props and costume accessories. Pearl crepe craft paper can be soaked in a small amount of water to create a dye for Easter eggs, white cardstock, and other materials.
1. Features of pearlized paper

(1) The surface pearl effect is easily destroyed

(2) low surface energy and poor adsorption performance to ink
Because the surface structure of mica and titanium dioxide (or other metal oxides) is smooth, and the paper surface is relatively smooth during the papermaking process (so that the pearlescent effect can better penetrate the coating into the human eye), thepearlized paper is more common than ordinary The surface energy of the whiteboard paper is much smaller, and the ink is less likely to adhere and absorb during printing, and is not easy to dry.

2. Structure of pearlized paper

The composition ofpearlized paper is the same as ordinary white paper, which consists of three parts: the bottom fiber, the filler and the surface coating. Unlike ordinary whiteboard paper, there are particles that have a pearlescent effect in the surface coating. The particles are composed of titanium dioxide (or other metal oxide) and mica particles, and the mica particles are formed by coating titanium dioxide (or other metal oxide), and the structure is in the form of flakes.

3. What problems can be caused by pearl paper printing?

(1) The pearlescent effect is easily lost, and printing is likely to form white spots, hair spots, creases and the like.

(2) Poor ink adhesion and poor drying result in low density of printed solids, loss of small dots, slow drying, easy to stick on the reverse side, easy to scratch, and the like.

"Children's mats" not designed for children are not good mats

Crawling is an indispensable behavior in infancy, and the importance of children's physiological development is self-evident. Perhaps it is just to see this feature. In recent years, a “floor mat” designed for children has seized business opportunities. More and more families choose to buy this kind of crawling mat for their children to play. . Of course, when the child is not playing, the mat still needs to be put away, so the most convenient floor mat is obviously spliced, and it only needs to be assembled when it is used. However, there is growing evidence that there are some hidden dangers in this type of child floor foam mat.

The hidden danger comes from a substance called "formamide". Thankfully, because of these products that consumers are not worried about, we have been scientifically chemical. Now let's talk about how this formamide comes from.

Children's floor mats, which are practical as a foam material, need to be made by a foaming process. The material commonly used for floor mats is EVA (ethylene-vinyl acetate copolymer) resin, which is particularly soft and has excellent processing properties. The floor mat is very competent and itself is safe. However, in the process of foaming, it is necessary to use a foaming agent to complete, so many manufacturers use a substance called "azodicarbonamide" (some media called azoformamide), at a certain Under conditions, it generates nitrogen to form bubbles in the EVA resin, which is the principle of the foaming process.

In fact, azodicarbonamide is also a food additive, which can play a role in whitening and toughening in flour. Its existence has also caused many controversies, so many countries have been banned. Because it is used as a foaming agent, it also produces a lot of by-products while generating nitrogen gas, and formamide is one of them, but it is not the main one. Studies have shown that it is cumulative in the body - not easy to excrete with the digestion residue, can only be slowly metabolized to formic acid and ammonium salts in the body, therefore, the continued intake of formamide, there are still many risks.

More critically, it has reproductive and developmental toxicity, which can have very serious adverse consequences for infants and young children. Studies have shown that when mice continue to inhale more than 300 ppm (or 0.03%) of carboxamide In 7-14 weeks, there will be obvious reproductive problems, and the weight will also drop. Combined with the continuous accumulation of formamide, if the child crawls on the toxic floor mat for a long time, the damage can not be underestimated.

For foamed EVA resin, in Europe, after reference to the experimental data, after many adjustments, the standard is currently determined to be no more than 200 mg/kg. This is not a difficult standard.

However, even if this standard is relatively loose, the domestic popular eva floor mat still can not meet the requirements. Some testing units have found that some products can reach more than 1,800 mg/kg, nearly 10 times higher than European standards. The main reason for this problem is that China has not yet established standards for this product, and the second is because the larger the amount of foaming agent, the smaller the density of the product, and the profit of the manufacturer can be obtained. Improvement, but behind this increase in profits, is a potential threat to the majority of children.

At the time when the domestic standards have not yet been established, as consumers, we need to be more vigilant about the products we buy, and we cannot buy three products without cheaper. Even if it is a regular channel product, we must ask more questions. When you buy some integral floor mats (the foaming process is different), we will get more protection for our safety.

DIY rainbow scratch art paper the easy way

Rainbow scratch paper, create the planets, sun, and any other pattern, kids will be amazed by the beautiful colorful pictures they create. Simple scratch the black coating and reveal stunning effects hiding just beneath the surface. Magical rainbow cardboard easy, safe, clean, and nontoxic, great for developing kids creative intelligence. Creative kids can jot notes, etch doodles, and make mini-masterpieces whenever inspiration strikes with this engraving cardboard pad.

1. First we covered paper with oil pastel drawings until the entire sheet was full of color.
2. Then we painted over the oil pastel with a layer of black BioColor paint.
3. Finally, we scratched our pictures and designs through the surface of the wet paint with toothpicks and Q-tips.

What makes this scratch art process easier than most… We used oil pastels rather than crayons and scratched our design through the wet paint which was both easier and quicker than if we had waited for the paint to dry.

Paper size: Smaller sheets of paper will be quicker to fill with color. I cut our color paper in half, but you could go even smaller.
Age: It’s important to fill the entire sheet with color, so this project works better with preschoolers on up who can/will do that. For toddlers, you can make the magic scratch paper for them and let them do the final step of scratching designs in the paper.
Oil pastels vs crayons: You can also use crayons, but oil pastels are easier and quicker, especially for younger kids.
Q-tips and toothpicks: We started with Q-tips in the wet paint for a wider line. Maia preferred the toothpicks…and Daphne liked to use both the Q-tips and toothpicks together.
Wet vs dry: We made our scratch art pictures and designs while the paint was still wet and it worked great. We tried letting some dry first and found that the paint flaked off more unevenly (see the lines I did at the left of the face above).
Paint type: The BioColor paint we used needed two layers to coat the oil pastel layer perfectly. We didn’t usually do two layers though and liked it fine with a bit of color peaking through. You can add a couple drops of liquid dish soap to make it coat the oil pastels more evenly although we didn’t at the beginning. We also tried acrylics, which coated better than the BioColor, and tempera paint.
We tested tempera paint vs BioColor paint with and without dish soap and did all the scratch art designs after the paint dried. The three at the top were made with tempera paint and Daphne did the scratch art, which as you can see is barely visible. The three at the bottom were made with BioColor paint and Maia did the scratch art.
I recommend giving this DIY scratch art activity a try with your kids!
