Chips are a lightweight, fragile snack, thus demanding exceptionally high standards in packaging. what is the process of chips packaging?
Chips packaging typically employs ten-head weighing packaging machines. The primary packaging process comprises five key steps: weighing, bagging, filling, sealing, and inspection.
1. Weighing
Upon completion of production, potato crisps are conveyed via an elevator to the feeding section of the ten-head weighing and packaging machine. The multi-head weigher employs high-precision sensors for rapid weighing, enabling it to:
- Automatically assemble the quantity of crisps closest to the target weight
- Maintain minimal measurement error
- Reduce repeated weighing, thereby enhancing production efficiency
- The equipment employs distributed weighing and a gentle discharge method, effectively minimising collision and breakage of the potato chips.
2. Bagging
Following weighing, the crisps are conveyed into the vertical bag-forming packaging machine. Here, the machine automatically forms the bag structure from roll film, encompassing:
- Unrolling of the bag film
- Shaping of the crisp packaging (either pillow-style or stand-up pouches)
- Automated completion of edge trimming and folding processes
- The fully automated bag-forming design ensures uniform and aesthetically pleasing pouches, establishing the foundation for secure packaging sealing.
3.Filling
The filling stage employs synchronised control to discharge weighed potato crisps into pre-formed bags. To minimise crisp breakage:
- Short drop heights or cushioning devices are typically utilised
- Optimal discharge angles and velocity control are applied
- Impact on the crisps is minimised throughout the process
- This operation demands high equipment stability to ensure the integrity of crisps within the bags.
4.Sealing
Upon completion of bagging, the process proceeds to the heat-sealing stage. The sealing machine employs heating to perform both transverse and longitudinal sealing of the packaging bags, ensuring:
- A secure seal to prevent air leakage
- A smooth, wrinkle-free appearance
- Extended shelf life and crispness of the crisps
- In certain factories, to preserve optimal flavour, nitrogen flushing is simultaneously applied, creating an inert gas environment within the bag.
5.Inspection
Following sealing, finished products undergo multiple inspection stages, including:
1. Weight Inspection
Automatic weight checkers weigh each bag of crisps; any abnormal weight triggers automatic rejection.
2. Metal DetectionProducts pass through metal detectors to prevent metallic contaminants from entering the food supply, ensuring food safety.
