The latest technology in film production

A good plastic package should not only pay attention to the selection of materials, but also consider the stability and diversity of the production line. This article describes a variety of the latest film and bottle production lines and processes.

Thin film manufacturing
Global bi-directional film manufacturers are looking for ways to produce more diverse films that have superior characteristics including mechanical properties, optical properties, shrinkage and barrier properties.

In recent years, DMT has been actively developing horizontal and vertical stretching technology for films because of the increasing market demand for such special films. The first to appear on the market is the simultaneous longitudinal and horizontal ratio mechanical stretching technique. This type of equipment has been widely used to produce high quality films.

The next step for equipment developers is to develop more flexible and effective systems. DMT has developed this new technology, that is, synchronous stretching ratio can be adjusted at will. The difference between this system and other existing systems is that:

* The system is a mechanical system that relies on DMT's proven continuous monorail, bearing pressure iron and lifetime lubrication chain technology; the oven design is the same as a conventional sequential drawing line; maintenance needs are no more than traditional sequential drawing lines The energy consumption of the drawing unit is similar to that of the sequence line; the output (production speed, width) is similar to the standard sequential biaxial drawing line.
In addition to better film properties, production costs and output are also important. DMT Synchronous Stretching System can produce vertical/horizontal slack high shrinkage film (80%), high barrier film (multi-polymer film), isotropic film, and can be used in BOPP, BOPET, BOPA, BOPLA, BOPS, BOPETG , BOPVC, BOPE and other films.

In the past five years, China has invested heavily in biaxially stretched film production equipment. Most of these equipment are used to produce general purpose films, namely BOPP, BOPET, and BOPA. Due to the large investment in new production capacity, a large number of Chinese film producers now doubt whether the market can absorb so much supply. Therefore, a new trend has emerged: investing in more specialty films. The supply and demand of such films are now balanced and long-term investment will be profitable.

DMT sees this development trend, and special films need to increase costs from Japan, Europe, and the United States, so DMT has developed a mechanical synchronization system MESIM, the film made of: BOPP smoke film, with isotropic properties and High shrinkage; Polyolefin film (mixed), high shrinkage (80%) for outer packaging applications; Optical film, such as LCD film, requiring scratch resistance; PET-based thick film, used as industrial and image Uses; high-grade BOPA film, used in the low bending requirements of the printing industry; BOPEN film; packaging with high shrinkage film, such as labels, sleeves.
