Shrink Film Wrapping Machine: Everything You Need to Know
Introduction
A shrink film wrapping machine is a packaging device that uses heat-shrinkable film to wrap products and shrinks it by heating so that it adheres closely to the surface of the product, providing attractive solutions for the food and beverage industry, publishing, electronics, pharmaceuticals, logistics and warehousing, etc. Flexshrink has more than ten years of experience in the shrink film wrapping machine.
How Do Shrink Film Wrapping Machines Work?
Before we start to explore the working principle of the shrink film wrapping machine, we need to understand its components. Generally speaking, a shrink film packaging machine consists of a seal bar, a conveyor system, a heat tunnel, and a control panel.
Seal Bar: A seal bar is used to cut and form a tight seal by applying pressure to the overlap of the film.
Conveyor System: Products are moved from one stage to the next on a shrink film wrapping machine via a conveyor belt.
Heat Tunnel: The heat tunnel is the most crucial part of the shrink film wrapping machine. The film covering the product is heated here and adheres tightly to the product.
Control Panel: The shrinking temperature, sealing time, sealing temperature, conveyor speed, and emergency operations can all be controlled by simple operations.
So, here is how it works: After the product is wrapped, the conveying system transports the product to the sealing bar for heat cutting and sealing, and then the conveyor belt sends it into the heat shrink tunnel for heating and shrinking, so that the heat shrink film fits tightly to the product.
Benefits of Using a Shrink Film Wrapping Machine
Whatever your product, you can expect the following benefits from using a Flexshrink shrink wrapping machine:
Professional Appearance: Shrink film fits the product tightly and has a smooth surface, which can greatly improve the aesthetics of product packaging. Transparent film can protect the product while allowing the product to be directly displayed to consumers, facilitating sales and bringing economic benefits.
Improved Protection: Sealed shrink packaging can effectively isolate dust, moisture, and other pollutants, ensuring that the product is in good sanitary conditions and minimizing the impact of the external environment on product quality. Film wrapping can also bind products firmly together to prevent them from scattering during transportation, and once damaged, they cannot be restored, which has the function of anti-tampering and anti-theft.
Cost-Cutting: The cost of shrink film materials is lower than that of packaging materials such as cardboard boxes and hard plastic boxes. The compact packaging of shrink film can significantly save storage and logistics space. In addition, Flexshrink’s fully automatic shrink film wrapping machine can also reduce your labor costs.
High Efficiency: Semi-automatic and automatic shrink film packaging machines eliminate the need for tedious manual packaging and heat sealing operations and can be seamlessly integrated with production lines, making the entire production process more efficient.
Excellent Flexibility: Shrink film packaging machines offer flexible marketing applications, allowing you to group and bundle your products and configure sales units flexibly. Printable shrink film can also be imprinted with exquisite marketing graphics, trademarks, and other promotional information.
Different Types of Shrink Film Wrapping Machines
To understand what kind of shrink film packaging machine is suitable for your project, here is some information that can help you:
Divided by Degree of Automation:
The degree of automation of the shrink film wrapping machine directly determines your production costs and efficiency.
Manual/Handheld Shrink Film Wrapping Machine
Handheld shrink wrapping machines are completely manually operated. The operator wraps the film around the product with a manual sealer, applies a simple seal with a hot air wand, and then heats the film with a handheld heat gun to shrink it. These manual shrink film wrapping machines are extremely inefficient and suitable only for very small quantities of packaging.
Semi-Automatic Shrink Film Wrapping Machine
The operator places the product on the machine’s table, which automatically seals and cuts the product. The operator then manually places the product into a separate shrink machine for heat shrinking.
This shrink film wrapping machine offers greater flexibility, allowing for instant product changes and adapting to small-batch, high-variety production. It’s a cost-effective choice for small and medium-sized factories, logistics centers, e-commerce warehouses, gift shops, and other locations.
Fully Automatic Shrink Film Wrapping Machine
The fully automatic shrink film wrapping machines are fully integrated into automated production lines. Products enter the machine automatically via a conveyor belt, and the entire process of film feeding, wrapping, sealing, cutting, and shrinking is completed automatically, eliminating the need for manual operation.
The fully automatic shrink film wrapping machines can significantly reduce labor costs, while their high degree of automation ensures consistent sealing and shrinking results for each package.
Divided by Sealing Methods:
The sealing and cutting method of the sealing and cutting machine determines the type of packaging and the applicable products.
L-Bar Sealer Shrink Film Wrapping Machine
The film roll of the L-bar sealer is located above the product and is pulled down to form an L shape. At this time, the hot air bar descends to complete the sealing and cutting at the back and bottom of the product, leaving the front and top of the product open.
The L-bar sealer is suitable for products with high height and large volume, and can be used for both semi-automatic shrink film wrapping machines and fully automatic shrink film wrapping machines.
Side Seal Shrink Film Wrapping Machine
When using the side seal shrink film wrapping machine, the product moves on the conveyor belt, and the film wraps the product from both sides. The heat sealing bar seals and cuts it vertically from both sides. Suitable for packaging products with regular shapes and low height.
Bullseye/Sleeve Shrink Film Wrapping Machine
When using the bullseye/sleeve shrink film wrapping machine, the film roll is folded into a cylinder, the product passes through the middle, and the transverse heat sealing bar seals and cuts the product in front and back, finally forming a sleeve-shaped package that is sealed on all four sides. It is commonly seen in multi-bottle combination packaging of beer and beverages.
Divided by Heating Methods:
The way to heat shrink determines the selection of film types and the final appearance.
Hot Air Circulation Shrink Film Wrapping Machine
The hot air is blown out by a high-power fan and circulated continuously in the tunnel to form a uniform hot air environment. Suitable for various types of films.
Steam Shrinkage Film Wrapping Machine
Using steam as a heat source for heating has a high thermal energy utilization rate, but it is specifically used for label shrinkage of PET bottled beverages.
Factors to Consider Before Buying a Shrink Wrapping Machine
Despite the versatility of shrink film wrapping machines, there are still many factors to consider when finding the best solution.
The purpose: What is your product? Is it a regular shape? What are the length, width, height, and weight of the product packaging? (Height is the most critical) This determines whether you need a tray-type or fully enclosed shrink film wrapping machine. The weight of the product determines the load-bearing requirements of the conveyor belt. Whether the product has good temperature resistance determines the choice of shrink tunnel and film.
Productivity: How many products do you need to wrap per minute or hour? This will determine whether you should choose a standard or high-speed shrinkwrapper, as well as its level of automation. If your production volume experiences seasonal peaks, you may also want to consider adding auxiliary equipment (such as checkweighers, feeders, discard arms, and labeling units) to increase production efficiency.
Films: What is the width and thickness of the shrink film you need? This determines the configuration of the film frame and sealing bar of the machine. The characteristics of the product determine whether you need a high transparency film or a film with an outlet, and also determine the power and heating method of the shrink film wrapping machine’s heating tunnel.
