Every process step a line does not have to perform is a step that cannot go wrong, cannot consume energy and cannot generate emissions. In conventional pre coated film production the primer stage sits between the base film and the EVA extruder, and it brings a coating station, a drying oven, solvent handling, exhaust treatment and a quality check of its own. This primerless base film removes that entire block of the process, because the bonding function is built into the film during its own manufacture rather than applied in a separate pass.
The practical effect on a running plant is measurable: one oven less to heat, one solvent stream less to handle, one coat weight less to control and one source of defects less to chase. It also shortens changeover between jobs, since there is no primer circulation to flush and no drying profile to re establish, which matters most for plants running many short orders rather than a small number of long runs.

The bonding function is built into the film, so the primer coater and its associated hardware are not needed in the pre coating line at all.
Without a primer coat there is nothing to dry, so the oven that would normally run continuously at pre coating temperature is switched off, which is the single largest energy saving in the change.
Primer solvents no longer enter the process, so solvent vapour load in the plant and the associated exhaust treatment demand both fall.
Primer streaks, skips, foam, contamination and coat weight variation disappear from the list of possible causes when a pre coated roll shows a bonding fault.
No primer circulation to flush and no drying profile to rebuild between jobs, which shortens downtime on plants running many short orders.
Incoming inspection focuses on the base film and the adhesive only, rather than on primer viscosity, coat weight and drying condition in addition.
Removing a coating station and an oven frees floor space and reduces maintenance and spare parts on the primer unit.
Material and energy cost is concentrated in base film and adhesive, which makes costing a job simpler and less sensitive to primer price and solvent recovery efficiency.
We are a manufacturer located in Hefei city, Anhui province, China, with our own BOPP and BOPET production lines and an annual capacity of 180,000 tons.
Our typical MOQ is usually 500kg, depending on the exact grade and specification you need.
Sample making takes around 3-7 working days. Mass production takes around 10-25 working days after order confirmation.
Yes, we can provide A4 sample sheets for free. For custom samples, a sampling fee may differ based on different specifications.
EXW, FOB, CIF and DDU are available. We also have a dedicated shipping agent to arrange sea, air and express delivery.
We usually accept T/T bank transfer with 30% deposit and the balance before shipment. Other payment methods are negotiable.
The main gains are one coating station and one drying oven no longer in the process, which cuts energy demand per tonne and removes the associated solvent handling. Actual savings depend on line speed, oven length and the primer system you use today.
