As a leading China corrugated printed box manufacturer, Shanghai DE Printed Box supplies the custom E|B flute corrugated mailers, mailing boxes, postage boxes. These boxes are widely used by the retailers and merchandisers for the delivery of their products to their customers.
Corrugated mailers are used for the postage purpose because of the good strength and durability during the delivery and transportation process. The spcial box structure makes it quite resistant to the rough handling. The E flute corrugated mailer is usually a typical E flute corrugated box. But when the mailer has a large size and extra strength is essential, it can be made of the 3mm thickness B flute corrugated box.
Some corrugated mailing boxes have just the kraft paper of the corrugated board without any printing. While most mailers or postage boxes are either flexo printed or litho printed outside. Besides the common corrugated mailer boxes printed only on one side, our client can also have a custom corrugated box printed inside and outside, which is printed on both side of the box.
There are 2 box styles that are commonly used for the mailing box, also referred to the mailer, postage box, mailing box, postage box, carton. One of the box style is the roll end tuck top box, the other one is the roll end locked front box, which has the better box closure. They are all made of piece of corrugated board, self-locked. Due to the double corrugated board wall on the left side panel, right side panel, and the bottom panel, the corrugated printed box is extremely strong, making it very suitable and ideal for the shipping and transportation. Therefore, we also call them mailing box, mailer, post box, postage box.
Besides, books and photo frames are usually packed inside the corrugated folders which are most cost effective because the books don't have a very strict requirement for the structure of the package.
B flute, E flute corrugated board is mostly used for the corrugated mailer box. It is 1.8mm in thickness for the E flute board and 2.8mm in thickness for the B flute corrugated board. Such a corrugated mailer are very suitable for the retail products, electronics products packaging and shipping. There can also be a white inner surface inside the printed box to make it more aesthetically pleasing.
The corrugated mailer usually has either the flexographic printing or the offset printing. Silk Screen Printing is also widely used for the simple printing of the texts, lines and patterns. The flexographic printing as show on the picture left is used for mailer box when you focus on a strong mailer and have no special requirement for the printing. While the offset printing is usually applied when a high quality printed picture on the box surface is needed. The costs varies a lot for flexo and offset printing.
Laminating and Varnishing are the mostly used finish for the corrugated printed box. They both comes in glossy and matt. The laminated printed box has the better strength, durability and is water resistant due to the thin transparent film outside. The laminating costs a little more than the varnishing. And the UV varnishing is more expensive than the ordinary glossy varnishing method.
