Standing doypack pouches are becoming more and more favored in the consumer market for windshield washer fluid products. It not only provides a better user experience when consumers try to refill their automobile with fresh cleaning chemicals, but also reduces the plastic material used for each individually filled bag.
Furthermore, attractive artwork design can be printed onto the standing bag with the highest standard of color consistency, which appeals to consumers in a feeling-good way. So, more and more packers are now seeking to fill windscreeen products into these standing screw cap bags.

Our company is a trustworthy manufacturer of standing spout doypacks located in Qingdao, China, for more than 10 years, and has been providing great standing bags for many brands and packers around the world, with near-zero-failure supplies in the long term. Here we are going to share our experience on how to choose the filling machinery to finalize the windshield washer fluids into a standing doypack.
Filling from the plastic spout or the top opening
One fundamental thing before talking about the machinery to fill the screw cap bag is to understand where to fill the washing liquids. As the plastic spout and screw cap system enables the standup bag to provide better re-sealing experience for the consumers, so the washing liquids can be filled from the plastic spout alternatively.

Filling from the corner spout

The doypack is held tightly on the rotatory tray, with the channel of the plastic spout trapped on the slots. The filling nozzle will be lowered into the inside of the package, and guide the washer fluids to the bag.
The advantage of filling products from this plastic spout is the great integration for the final package, as the doypack is finalized with all edges well sealed, and the closure is separately supplied to the customer with the doypacks.

After fluids filled, the closure will be screwed onto the spout, with counterfeit purpose.
Filling from top opening

The top edge will be left open when the standup pouch is supplied to the customer, and when products are going to be filled from the top opening, the efficiency can be largely improved. The top opening can accommodate a filling nozzle with a significantly larger inner diameter, allowing for a greater volume to be filled within a certain time frame.
When we figure out how to fill the doypack, then we can go on with our discussion on how to choose an acceptable and money-making filling machine to fill the windscreen washing chemicals into the standing spout doypack package. As there are various filling machineries in the market, we are going to share some of our experience and reliable machinery for your reference.
