Flow Packing Machine – Definitive Guide
Flow wrapper is mainly used for single or multiple solid packaging. It is also called a horizontal flow wrapping machine (HFFS), which is a type of plastic film packaging machine. Chinese flow wrapper manufacturers and users are used to calling it an automatic pillow packing machine.
Flow wrapper operation process
The flow wrapper adopts positioning sealing and cutting during packaging. In packaging production, due to the positioning color code printed on the packaging material, the error between the stretching of the packaging material and the mechanical transmission, the packaging material is predetermined. Sealing and cutting parts may deviate from the correct position and cause errors.
In order to eliminate errors and achieve the purpose of correct sealing and cutting, packaging design must consider the problem of automatic positioning. To solve this problem, the design of a continuous photoelectric automatic positioning system was completed according to the positioning standard of packaging materials. According to the error compensation working mode, the continuous photoelectric positioning system is divided into two types, front and rear, brake type, and synchronous transmission of two transmission systems.
Simply put the job of the flow wrapper is to wrap the product with a layer of film, like this:
1. Advantages of flow Packaging Machine
When you need to pack and mark a large number of the same products, a flow wrapper machine can help you pack efficiently. Unlike carton or shrink packaging, flow wrapper packaging can block air, and the product shelf life will be longer. Besides, film packaging can effectively block dust, and the packaged products are easier to place.
The contribution of nitrogen in the food field is great, as a leading flow wrapping machine manufacturer, we have added this technology to the flow wrapper to fill the food with nitrogen at the same time so that the food can be stored for a long time. For some long-term mass-produced products, such as chocolate, candies, biscuits, etc., we can provide professional packaging solutions to improve the automation level and productivity of the factory.
The information that needs to be printed such as the production date and batch number is essential for the packaging of some products. In the application of flow wrapper, we can directly add this function. For some special products, such as shisha tobacco, plasticine, nougat, etc., we can even use dedicated mixing, cutting, and packaging production lines. For products that require secondary packaging, our flow wrapper can be customized to connect some machines, such as cartoning machines.
2. Limitations of Flow Wrapping Machine
This machine is suitable for solid-shaped products and is not as suitable as a vertical packaging machine in the applicability of powder packaging. And the form of direct liquid filling is completely unsuitable.
In many cases, product upgrades represent cost expenditures. Although the price of standard machines has dropped to a certain extent every year, for some special customized packaging lines, the cost of expenditure is still considerable.
I have to say that in some food applications, such as chocolate and biscuits if smart packaging is used, the area that needs to be occupied will be huge. Technology pushes people forward. They can’t be perfect, but the convenience they bring us is huge.
3. Several styles of Flow Wrapper Packaging
Here are several sealing forms that the flow wrapper can change through the modification of the tool.
1) The most common form of sealing tooth-shaped sealing
As it is conducive to consumers to open the package quickly, tooth-shaped sealing is the most common sealing form in the current market. This sealing method is completed by a combination of a toothed cutter and a striped sealing seat.
At the same time, under the condition of the same tool seat, the toothed knife can be replaced with a flat knife, which is also a very common packaging method.
2) Packaging with holes
Some products need to be hung on the shelf for display, so we need to punch a hole in the packaging. It is not difficult to achieve this kind of packaging, we only need to open a hole on the knife holder and equip it with a punching mold. And the shape of the hole can be different.
Airplane-shaped hook hole
Flow wrapper holder with round hole shape
3) Seal pattern
The edge-sealing effect with texture can not only improve the aesthetics of the package but also the sealing performance will be greatly improved. We usually have parallel lines, but there are actually many kinds of lines.
Usually, we recommend the best packaging form based on the customer’s product or packaging material. Generally, in some general scenarios, customers can customize the sealed form according to their preferences.
4. The Material used in the Flow Packing Machine
In addition to the machine itself, the materials used in the packaging are also critical, which involves the stability of the machine, the aesthetics of the product, the cleanliness, the aesthetics of the packaging, and so on. So what kind of packaging materials can be used for flow wrapper?
The general pillow packaging machine uses 7 kinds of films: OPP film, CPP film, OPP composite PE, OPP composite CPP, PT composite PE, aluminized film, paper film (laminated film).
Next, we will score some major materials:
|Material||Feature||The main Purpose|
|Moisture Resistance||Air Barrier||Oil Resistance||Low Humidity Resistance||Transparency||Anti-UV||Formability||Heat Sealability|
|OPP/PE||★||○||○||★||★||×||○||★||Biscuits, instant noodles, medicine (tablets)|
|PET/PE||★||★||★||★||★||×||○||★||Steamed, frozen, rice cake|
Note: ★ is excellent; ○ is good; △ is fair; × is bad; the friction coefficient of all packaging films is the highest 7
After intuitive comparison and understanding of the characteristics of the packaging film, we can choose the film that suits our products. For example, packaging food and medicine generally requires airtight film. At this time, OPP, PET, and aluminized film will be better choices.
5. Packaging film width and unit price calculation
Taking opp/CPP packaging film as an example, you first need to understand the length, width, and thickness of the product (unit is mm). Such as product: length 65mm width 50mm thickness 5mm.
Then the formula for calculating the length and width of the packaging film required by the product:
Packaging film length: product length + product thickness + horizontal seal 30 = film length
Packaging film width: (product width + product thickness) × 2 + vertical seal 30 = film width
It can be concluded that the length and width of the film used in the product are: 100mm+140mm.
Based on this indicator, we use a formula to calculate the unit price of the packaging film.
At this point, first, convert the above calculation result of film length and width into m
Film length × film width × 0.00005 × packaging film price per ton = single packaging film unit price
(Note: 0.00005 is 5 c)
First, convert the price of 4,300 a ton into a unit price of one kilogram
Unit price per kilogram ÷ unit price of a single packaging film = packaging quantity per kilogram
Total number of products ÷ number of packages per kilogram = total number of kilograms of packaging film to be purchased
Set the total number of products to 1,000,000
The total kilogram quantity of packaging film that needs to be purchased × the unit price per kilogram equals = the total price
PS: The above price is an assumption, please refer to the actual price
6. How to Choose the Right Flow Wrapping Film?
Finding the right type of film and how to use the film is as important as choosing the packaging method. Flow packaging can hold many types of products; from candy bars to medical devices, flow packaging provides a wide range of benefits for production managers. Factors such as cost-effectiveness, minimal waste and high output make flow packaging the first choice for packers.
Although it is important to determine whether flow packaging is the correct packaging technology for your product, it is equally important to choose the correct film. The flow packaging process wraps the product in a transparent or printed polyolefin, polypropylene or laminate film to form a three-sided sealed package to produce a light and flexible package. When considering the type of film used in flow packaging, there are several factors to keep in mind.
- Double membrane-running double membrane on one machine is both efficient and flexible.
- Selection -a balance should be struck between quality, performance, efficiency and cost. You should always choose films based on product and packaging characteristics.
- Feature questions to consider-should you consider oxygen transfer rate (OTR), water transfer rate (WTR), or modified atmosphere packaging (MAP)? Or is this application just a cover or group of products/products?
- Further factors-sealing method, throughput, preferred packaging style, product heat sensitivity, quality, budget, output, and required sealing jaw profile are factors to consider when choosing the correct film.
- Product Type-There are many products suitable for flow packaging. For example, in-store production bags, baked goods, bagged boxes (for films containing products inserted into folding cartons or boxes); cooking bags, over-packaged products (such as bell peppers), candy and candy packaging, or meat, poultry And seafood packaging.
There are a variety of commonly used flow wrap films:
- Polypropylene series (PP)-This kind of film is usually used in snack foods, candies, baked goods, etc. It can be transparent, printed or opaque. It is combined with the coating to help protect the film and the product. The protective effect of PP on moisture and oxygen is limited.
- Polyethene series (PE)-PE includes low-density, linear low-density and high-density films. Low-density film and linear low-density film have similar characteristics: good transparency, high flexibility, and can be heat-sealed using a special sealing system. Both low density and linear low-density films are used in the stretch and shrink packaging, bags, pizza, baked goods and other similar applications. High-density polyethene has low transparency and is used together with EVA to package frozen foods, biscuits, bread bags, cereal box liners, etc.
- Polyester film (PET)-Polyester film is usually combined with other films as an outer layer. Potato chips and pretzels in metalized packaging or culinary packaging are common uses. PET lamination provides lightweight, water resistance, heat reflection and ultraviolet light. It preserves freshness and flavour while having the scratch resistance properties of retail and transportation.
The Right Seal
- Three common sealing elements-they are time, temperature and pressure. Changes in one element affect another element.
- Jaw seal-In addition to the sealing element, the type and method of jaw seal also need to be considered. There are many types to consider, and each type has its own unique advantages and disadvantages.
- Flow chart packages performance-when variable changes, it needs to be adjusted. Seal jaw wears, material changes or changes, sealing time or equipment speed changes are variables that need to be considered.
- Hot and cold film sealing-the use of hot or cold film sealing depends on individual product characteristics, material cost constraints, production throughput (capacity/speed), required seal strength or integrity and required film barrier properties ( Ultraviolet rays, oxygen, etc.).
- Cold Seal-This kind of seal is created by pressing the film together using a substrate and adhesive layer. Cold sealing cannot protect the product like heating sealing, and it is more susceptible to environmental factors. However, heat-sensitive products, such as chocolate, need to be cold sealed.
- Heat sealing-Heat sealing is the best choice for high integrity sealing. The temperature range is the key: the wider the effective range, the less chance of seal failure.
7. Things to note when purchasing packaging film
When purchasing packaging film for your flow wrapping packaging, there are some things you need to know first.
- Choice of packaging film thickness
Generally, we recommend the use of packaging film with a thickness of 3.0c-8.0c. Based on product characteristics, such as food, we generally recommend a film thickness of 8.0c.
The thickness of the film is very important to the sealing performance and packaging strength. A film that is too thin is easy to break, and a film that is too thick is not easy to seal.
- Tracking the printing of color marks
For the packaging effect of the product, we usually use printed film or transparent film. But in actual application scenarios, not all machines are applicable. For example, the reverse stretch film flow wrapper (using the packaging film as the driving force to pull the product forward) must be applied to the packaging film with color code printing. If there is no color code, the cut-out bag will be different in length.
- Color of the color code
Our common color code is black. This is to better distinguish the color code tracker when packaging on the flow wrapper. Therefore, the color of the color code is not necessarily black but should have a stronger color than the color of the packaging film
Everyone is familiar with flow wrapper equipment. This equipment has been manufactured and launched on the market since the 1970s. I believe that people are more willing to buy more intelligent flow wrappers with innovative ideas.
