Potato chips have very high packaging requirements because they are thin, crispy, and easily damaged by moisture and pressure.  They also rely heavily on attractive packaging for brand image and presentation. Therefore, choosing the right packaging format and equipment is crucial for ensuring product quality, extending shelf life, and enhancing market competitiveness. So, what packaging is used for chips?

In actual production and sales, pillow-shaped bags and stand-up pouches are currently two common packaging methods for potato chips. These two packaging formats are very suitable for lightweight, fragile puffed foods like potato chips.

1. Pillow Bag Packaging

Pillow bag packaging is a widely used packaging format in the potato chip industry, especially common for standard-sized potato chips sold in supermarkets and convenience stores.

After packaging, it presents a “pillow” shape with a bulging middle and sealed ends.

It usually uses composite film materials, such as BOPP/CPP, PET/PE, etc.

It can be used in conjunction with nitrogen gas packaging.

2. Stand-up Pouch Packaging

With consumers demanding greater convenience and higher quality packaging, stand-up pouches are becoming increasingly common in the potato chip industry, often used for mid-to-high-end products or family-size and sharing-size bags of chips.

This packaging format features a folded base structure, allowing it to stand upright on store shelves.

It can be designed with a resealable zipper closure for repeated opening and closing.

Common Equipment Used in Potato Chip Packaging: Multihead Weigher Packaging System

Whether for pillow-shaped bags or stand-up pouches, multihead weigher packaging equipment is almost a standard solution on automated potato chip production lines. A typical configuration usually includes: a multihead combination weigher + a vertical form fill seal machine.The multihead weigher typically uses vibrating plates, buffer hoppers, and optimized discharge structures. The material handling process is relatively gentle, effectively reducing the breakage rate of potato chips during weighing and dispensing, ensuring the appearance of the finished product. Moreover, it is not only suitable for potato chips but also for other puffed foods, nuts, candies, biscuits, and other products. Different specifications and weights can be switched through parameter adjustments, offering high flexibility.
