Primary packaging is unique

Pw 9041 3b Sb Pouch Closeup

Siptop Packaging Inc. gets its name from its patented Siptop pouch. No straw is needed. The user simply tears off the top—notches on either side of the spout make it easy—and sips directly from the pouch.

Convenience and fun were primary drivers behind the concept. So was source reduction, as the pouch weighs considerably less than glass or rigid plastic alternatives.

The pouches are formed and filled from a roll that holds about 18,000 impressions. Supplied by Packall Packaging (www.packall.com), the pouch material is typically polyester/nylon/polyethylene heat-seal layer for Siptop’s own-brand Rip ’n Sip juice drinks or Northern Pure purified water. The outside polyester is reverse-printed flexographically in four or five colors. Soon to be introduced is an Iced Vodka, which incorporates a center layer of metallized nylon for extra graphic pop. Total film thickness in each case is about 4 mils.

Each twin-head filling system on which Siptop pouches are produced was designed in-house and cranks out 120 pouches/min. “No other vertical form/fill/seal machine out there makes a seal that is curved,” says Joyce. “They all seal and cut along a straight line, which is considerably easier. But these pouches are filled two at a time in a horizontal orientation, so the shape of the sealing jaws has to reflect the curved sides of the pouches. The liquid is released at a constant rate and the film is timed so that we get the proper volume in each pair of pouches with each cycle.”
