Super Calendared Kraft paper is also known as SCK Release Paper and is the second most commonly used printable glossy release pattern. It's made by taking a high-quality calendared fine kraft paper and covering one of its surface with industrial silicone release adhesive. When the adhesive dries, it leaves a smooth, flat edge along the paper's surface and that's where the ink will be drawn.
There are three types of super calendared kraft paper that are widely used for prepreg. The first is high-quality polyester stock. This type of stock has excellent colorfastness and durability which makes it a good choice for many printing tasks. A major downside to using this type of stock is that it tends to curl up or flake, so you'll want to apply plenty of pressure when pressing down on the paper's edge to help keep it from folding.
The next type of high-quality polyester stock used in super absorbent kraft paper features high wet strength, which means it can withstand lots of wear and tear. However, the drawback to using this type of stock is that it's more expensive than the previous two. Its absorption capacity isn't as high as the first two, but it still delivers quality prints with excellent colorfastness. One downside to using high wet strength paper is that it tends to crush easily when printed on, so it's best to use it for bag patterns or other small areas.
The third variety of high quality kraft paper features low thermal strength. Although the sheet isn't as durable as the previous two varieties, it does have excellent colorfast qualities. The biggest problem with using this kind of kraft paper is that it crumbles easily when printed on, but it's still one of the best bargain brands on the market. Because the kraft paper's strength lies in its colorfast quality, it can't be printed on over-high-gloss pigments, so it will only achieve excellent color inks if it has a very low internal ink concentration.
Super absorbent kraft paper's best quality lies in its strong adhesion properties. When printed on, the high-quality paper will stay together as a well-impared package even after being bundled up with a lot of loose items. The paper's surface also has very good distribution of ink across its surface, which helps to guarantee top-quality printing results no matter what the final output might look like. As this type of packaging is used for shipping purposes, it's absolutely crucial that the final delivery is as efficient as possible. Otherwise, shippers won't want to bother with sending any packages at all, since the time it would take for them to prepare a package for shipment on this kind of paper is simply not worth it.
In order for a given package to remain on-top of the list of best sellers, the bundle should have excellent quality printouts and packaging. Super Calendared Kraft is one type of kraft paper that does just this. Aside from being able to maintain its wet strength property without losing its excellent ink composition, this kind of packaging will last longer than the average papers because it's made out of polyester instead of acid-based core stock. This means that when it comes to getting the most out of these papers, buyers should always stick to choosing calendared papers.
