Sauce in a pouch

INDUSTRY BACKGROUND AND CORE CHALLENGES

With the growth of the pre-prepared food, seasoned food, and industrialized catering sectors, products such as ketchup, salad dressing, and chili sauce are increasingly being packaged in pouches. Pouch packaging offers advantages such as being lightweight and efficient while entailing lower transportation costs, making it widely used in food processing, catering, and retail markets.

However, due to the flexible and easily deformable nature of pouches, high-speed production lines can encounter issues such as under-filling, weight deviations, packaging damage, and foreign object contamination. Traditional manual spot-checking struggles to meet the demands of continuous production; therefore, automated in-line inspection is required to monitor product weight and detect foreign objects in real-time, enabling the prompt rejection of non-conforming products and thereby enhancing quality control and production efficiency for pouched sauces.

  • Back-seal Bags

SCENARIO 1: Spouted Pouches

Application scenarios: Large-capacity catering-grade salad dressing, ketchup, blueberry jam, black pepper sauce, etc.

 

Key pain points

Misaligned nozzle cap: An improperly tightened nozzle cap can cause the liquid to burst during transport due to compression.

Recommended model


Test items

Camera Defect Identification: The vision camera captures images of the nozzle, liquid level, and inkjet printing area, and compares and rejects products with high caps, crooked caps, low liquid levels, or incorrect inkjet printing. The detection content is configurable.

SCENARIO 2: Packs & Back-seal Bags

Application scenarios: standard ketchup packets for takeout and fast food, mustard packets with back seals, and instant noodle sauce packets.

 

Key pain points:

Leaking of sauce due to poor sealing: Thick sauce can easily get stuck at the heat-sealed part of the bag or the welded part of the nozzle, causing poor sealing and leakage of oil and gas from the whole bag.

Poor packaging and cutting: High-speed multi-row packaging machines often experience problems such as bags not being cut properly and serrated edges tearing.

Pattern/coding misalignment: The film conveyor belt deviates, causing the inkjet to be printed on the sealing edge.

Underweight bagged products and packages that failed to undergo sauce filling passed through the production line.

Recommended model


Test items:

Sealing and edge sealing inspection: Visually identify asymmetry in the upper and lower sealing dimensions, skewed cutting, and bag-connecting phenomena.

OCR traceability coding: High-speed reading of the production date on the surface of soft bags to reject missing or illegible items.
