Let's get to know the types of corrugated paper.
In general corrugated flutes that are larger in size will have higher strength and can support more shocks While smaller corrugated flutes are easier to form. get a corner that is sharper and make the printing work on the box more beautiful one sheet of corrugated paper May consist of corrugated flutes of various sizes mixed together. to get beautiful printouts coupled with higher strength Both the pressure various impact forces and the thickness of the corrugated sheet.
Today we will learn about different types of corrugated cardboard.
A-flute - highly stackable + good internal content protection.
Flute A is the original and largest wave. Therefore, when assembled with the inner and outer surface of the paper, it will have a thickness. of corrugated sheets the most with 36 flutes per foot length when using A flutes to produce corrugated boxes. will be able to withstand the most shocks and pressures Therefore, it is suitable for packing fragile items due to the high strength level of A-flute. Able to bear a lot of weight and pressure, A-flute is therefore applied in a variety of applications according to customer needs.
B Flute - Good puncture resistance + Highly used + Suitable for canning.
B flute is the second flute used in the corrugated industry. It has a lower height than A flute and has more flutes per foot length. B flutes have 50 flutes per foot, which means B flutes have more points of contact with the box surface than A flutes, making B flute corrugated sheets have a floor. Harder and smoother skin This will result in beautiful quality printouts. When used to make a die-cut box, it will be a beautiful box. It has high pressure resistance properties. In addition, B-flute is suitable for use with high-speed automatic packaging machines. It is also commonly used to produce pads, partitions and other components. Inside the box as well. In addition, B-flute is also suitable for packing products in canned packaging. Making complex die-cut boxes and drink tray Generally, B-flute is usually combined with lightweight liner board. However, heavy-weight liner can also be fused with B-flute as required.
C Flute - stacks and protects goods + most commonly used + suitable for glassware, furniture and dairy.
C Flute was later invented to combine the differences between A Flute and B Flute. C Flute has 42 C Flute per foot length and is less thick than A Flute. But more than B flute, C flute has the property to absorb impact. pressurization and print quality Blend together perfectly, so C-curtains are the most popular and used. Compared to other corrugated flutes, approximately 80% of today's corrugated packaging Made from C-flute corrugated paper.
E-flute - Lightweight micro-flute + High quality printing + Suitable for die-cut boxes.
E-flute has 94 flutes per foot length, which gives E-flute corrugated board a very high impact resistance. and has a smooth surface As a result, the print quality is also very high. E-flute thickness is only 1/4 of the thickness of C-flute. which saves storage space Due to its thinness and impact properties, E-flute can be used as a replacement for corrugated boxes. or fiber packaging. E-flute applications include cosmetic boxes, glassware, porcelain. and various fragile appliances Nowadays, E-flute boxes are becoming popular to produce more pizza boxes. Because customers want boxes that are worth the price. beautiful print and able to protect the product well.
F-curl - Slim.
F-curl is very small. It is only half the thickness of E-flute. At present, F-flute is becoming very popular in the corrugated industry. F-flute is the newest flute that has been used. developed by Europeans as an innovator in order to produce a packaging with elements Less wood fiber (fiber) composition Manufacturers can reduce the amount of wood fiber in packaging by using F-flutes. In this way, we can produce boxes with higher strength. And it can also reduce the amount of dry waste that goes to landfills. In Europe, F type is used for special packaging, trade fairs, jewelry boxes, cosmetic boxes. and shoe box In the United States, McDonald's has used F-curls for Big Macs. In addition, Dairy Queen also uses F-flutes to pack sandwiches and hot dogs.
