Potato chips are undoubtedly one of the most popular snacks in the world. From classic flavors like original, barbecue, sour cream & onion, and salt & vinegar, to creative tastes such as garlic prawns or seafood-inspired seasonings, potato chips continue to win consumers’ hearts globally.
Behind every crispy chip is a production process shaped by decades of technological innovation. But what did potato chips production look like before modern automated lines existed? Let’s explore the evolution of potato chips manufacturing—from manual processing to today’s fully automatic production lines.
1. Manual Potato Chips Production Before the 1920s
Potato chips originated in 1853 at a hotel in the United States. According to popular history, chef George Crum created the first potato chips after a customer complained that fried potatoes were sliced too thick. Crum responded by slicing the potatoes extremely thin, frying them until crispy, and adding salt. Unexpectedly, the dish became an instant hit.
During this early period, potato chips were mainly produced by hand. Potatoes were peeled, sliced, fried, and seasoned manually. Production was limited to small restaurants and local grocery stores, and output remained low due to the lack of machinery.
2. Semi-Automatic Potato Chips Production (1920s–1980s)
As potato chips grew in popularity, the industry began adopting mechanical innovations to improve efficiency and consistency.
In 1920, Herman Lay introduced a mechanical potato peeler, greatly improving peeling speed and labor efficiency. This milestone marked the transition toward semi-automatic potato chips production.
Another major breakthrough came in 1926, when entrepreneur Laura Scudder pioneered sealed packaging using waxed paper bags. This innovation helped protect chips from moisture and breakage during transportation. Later, cellophane and glassine bags further improved packaging quality.
In the 1950s, Joe Murphy, founder of the Irish crisp brand Tayto, developed modern potato chips seasoning technology, allowing manufacturers to add various flavors consistently and at scale.
These developments laid the foundation for mass production of potato chips and expanded their availability worldwide.

3. Fully Automatic Potato Chips Production Since the Late 1980s
From the late 1980s onward, potato chips manufacturing entered the era of full automation.
Key technological advancements include:
Microprocessor-controlled weighing systems (1980s) for precise portioning
Optical sorting technology (1990s) to remove defective potatoes and chips
Nitrogen-filled packaging (introduced in 1995) to preserve freshness and extend shelf life
Modern potato chips production lines integrate washing, peeling, slicing, blanching, frying, de-oiling, seasoning, and packaging into a continuous, automated process. Packaging materials now include PP, PE, PVC, HDPE, PS, ensuring safety, durability, and extended freshness.
These innovations enable manufacturers to meet large-scale market demand while maintaining stable quality.
