Flow wrapping has become a widely adopted packaging method for both large companies and small start-ups.
Its numerous advantages have piqued the interest of many, prompting them to delve into the mechanics and benefits of flow wrappers.
In this article, we will delve into the intricacies of flow wrapping, compare it to other packaging methods like overwrapping, and highlight why it could be the perfect choice for your business.
Flow wrapping involves placing a product on a sheet of packaging film, horizontally transporting it, and sealing both ends.
The most common type of flow wrapper is the horizontal flow wrapper, which is also referred to as horizontal bagging, fin seal wrapping, crimp seal wrapping, or pillow pouch wrapping.
On the other hand, vertical form fill seal packaging entails vertical movement of the product.
To create a flow-wrapped product, a flow wrapper machine carries out the following steps:
The speed of flow wrapping can vary significantly depending on factors such as the machine used and the size of the packaging.
Entry level and semi automatic machines typically produce 50 to 100 packages per minute
while high-speed fully automatic machines can achieve upto 150 to 600 packages per minute.
When it comes to costs, flow wrap machines can vary widely based on the model and features. Machines suitable for small start-ups can range from 4,000 to 10,000. The primary expense in flow wrapping lies in the machine itself, with the cost of packaging materials, such as polypropylene film, being relatively negligible.
Flow wrapping offers numerous advantages, including:
Flow wrapping primarily caters to solid products, with common applications including biscuits, cookies, chocolate bars, candy bars, tissue packs, frozen meats, tea boxes, and baked goods.
There is a wide array of flow wrapping machines available, catering to different needs and budgets.
Flow wrapping utilizes various film materials, including heat sealing, composite, mono, and paper-based wrap. The choice of material depends on the specific product being packaged.
Flow wrapping and overwrapping are two distinct packaging methods. Flow wrapping is typically preferred for primary packaging, while overwrapping is better suited for secondary applications.
Flow wrapping offers advantages such as speed, efficiency, and hygiene, while overwrapping provides versatility, aesthetics, odor locking, and tamper-proofing.
Flow wrapping stands as a versatile and efficient packaging method with a multitude of benefits. It is an excellent choice for primary packaging applications, while overwrapping is more suitable for secondary uses.
If you are considering automated packaging solutions, it is crucial to explore the range of available machines, taking into account factors such as cost, speed, and compatibility with your specific products.
