Everyone wants to live in a sustainable world. This includes being environmentally responsible in our work every day.

In the flexible packaging industry, most of the sustainability efforts tend to focus on materials.  Designers and researchers are always searching for materials that come from renewable sources, are reusable in some way, can be easily recycled, or are compostable and/or biodegradable.  A great deal of effort is also concentrated on reducing the overall amount of packaging by down gauging as well as eliminating layers and environmentally unfavorable materials.

While these efforts are all beneficial, an often overlooked opportunity for sustainability in flexible packaging is the manufacturing process itself.  To manufacture flexible packaging in the most sustainable manner possible, one can utilize solvent-free adhesive lamination technology, also known as solventless lamination.  The laminating adhesive used in this process is a two-component polyurethane.  These two components must be mixed together in the appropriate way to form a useful adhesive that will bond the material layers to each other, forming a flexible packaging substrate.  The manufacturers of these adhesive components control the viscosity properties of the final product in such a way that solvents are not required to maintain the material as a liquid; hence, solvent-free laminating machine is the inevitable outcome of scientific and technological progress.

Ruian CHANGHAI machinery manufacture Co.,Ltd (original named as DONGHAI Machinrey) is a professional manufacturer of solvent based dry laminating machine since 1987 and has sold our machines to 80% Chinese customers and hundreds of countries all over the world in the past 30+ years. In 2017, CHANGHAI machinery together with Korean professional coating machine manufacturer BARAM ENG CO.,Ltd introduced the technology of high speed solventless laminating machine from Korea. We established the company Wenzhou Shengtian Machinery Manufacture Co.,Ltd. and created our new brand for our solventless laminator- “SSEN”

   SSEN brand Solventfrees Laminating Machine is a product researched and developed by our company combined with the gradually matured solvent-free laminating technology. It’s based on the characteristics of the solvent-free laminating process itself, especially the problems such as low initial adhesion and difficult to control the amount of glue. In order to solve such key problems, many targeted innovations have been carried out in our machine including the mechanical structure, control methods, safety protection and appearance design. It is suitable for high-speed lamination of different types of films, paper and aluminum foils. It has the advantages of high efficiency, good performance and solvent residue-free.

 The full set of technical drawings was completed by Korean technical team which is led by Mr.Shaun Youn, the assembly work of the whole machine was led by Korean assembly technician team and mutually completed with the efforts of our domestic technical team. Machine frames and 90% machine parts are processed by CNC and imported from Korea and Japan. It is currently the most advanced and fastest solventless laminating machine in China.

Main Feature:

Ø  Accurate coating amount control and easy adjustment;
       Independent servo motor drive and linear independent adjustment enable the operator to accurately control the coating amount, and the adjustment is convenient with good replicability.

Ø  High Laminating Quality
       The material path has been carefully laid out, especially the use of a five-roller transferring coating mechanism, three-roller laminating mechanism, mirror surface cooling mechanism and frequency conversion motor taper rewinding mechanism guarantee the uniformity of lamination and rewinding.

Ø  Highly User-friendly
      Reasonable layout of the control panel and the use of pneumatic observation protective device make the operation of machine very convenient.

Ø  Machine safety is good, stable and reliable;
     As the main electrical components comply with CE safety standards, critical components are strictly handled, making the machine safe and reliable, it still can run smoothly at high speeds.

Ø  Easy operation
    Not only the above-mentioned perfect hardware structure, but also equipped with process method and other software support, the combination of software and hardware enable users to quickly master the use of equipment, effectively reduce the various consumption before production.
