Automatic High Precision Potato Chips Weighing Packing Machine Vertical Packaging Machine

Product Overview

For potato chips and other snack products sold by weight, packaging accuracy directly affects profitability. Under-filling risks regulatory penalties and customer complaints; over-filling gives away product. This Junyao vertical form-fill-seal packaging machine, paired with a high-precision multi-head weighing system, delivers the weight accuracy that snack producers depend on.

Manufactured at Xing Junyao's 13,000 m² Taizhou facility, the system combines a multi-head combination weigher with a continuous-motion vertical packaging machine. The weigher selects the optimal combination of weighing buckets to hit the target weight with minimal give-away, while the vertical machine forms, fills and seals bags in one continuous cycle. The system is proven across installations in over 25 countries since 2014.

Key Features

1.High-precision multi-head weighing — combination weighing technology selects the best bucket combination to reach target weight with minimal give-away, protecting margins on high-volume snack lines.

2.Continuous-motion VFFS — rotary sealing jaw design eliminates start-stop inertia, enabling higher speeds and reducing mechanical wear on drive components.

3.Gentle product handling — specialized infeed and filling chutes minimize chip breakage, a critical factor for potato chips where whole pieces drive perceived quality.

4.Multiple bag formats — pillow bags, gusseted bags and quad-seal bags with quick film-forming collar changes (10–15 minutes).

5.Hygienic washdown design — 304 stainless steel frame and IP65-rated electrical cabinet for washdown environments, designed for food factory hygiene protocols.

6.Easy integration — industry-standard weigher communication protocols allow pairing with your existing weighing system or a new unit.

Applications

Potato chips, corn chips, tortilla chips, snacks, nuts, and other free-flowing food products sold by weight.

Q:How much product give-away can I expect?

With multi-head combination weighing, typical give-away is 1 to 2 grams on a 200 g target — significantly less than single-head or volumetric filling. The exact figure depends on product piece weight and the number of weighing heads.

Q:Will the machine break potato chips during filling?

The filling chute is designed with gentle transitions and minimal drop height to protect chip integrity. Whole-piece presentation is critical for snack quality perception, and the system is engineered with that priority.

Q:Can I use my existing weighing system?

Yes. The machine uses industry-standard communication protocols, so it can be paired with most existing multi-head weighers or a new unit from our recommended suppliers.
