What is the smartest way to get the most out of your stretch film?

You drive home after work, if there’s no gas… . A gas station that sells gasoline at $3.50 a gallon will be noticed that it sells another kind of gas for $1.50 a gallon. So, what’s your choice? Which platform are you going to? This is an obvious one. You can get the most out of it by paying the least.

While we all know that such deals are rare, it is also possible to use another deal to stretch the film economy. It’s ok to spend $36 on 6,000 feet of film, or $36 for 18, 000 feet of film. What are your options at this time? The latter may be a more likely decision. If you want the deal, pre-stretching is necessary. It can bring the greatest benefit to you.

The process of extending the membrane is pre-stretching, and the membrane yield can be improved a lot. This happens when the two rolls of the film delivery system rotate, which is two different speeds, so the film stretching is caused. The standard of most semi-automatic fpc1 is pretensioning membrane conveying system.

We can give you an example, if it’s one hundred percent of the pre-tension, 6000 feet of the film will change, will be 12000 feet, if it is 200% of pre-stretching, 6000 feet of film changes again, into a 18000 feet of film, and so on.

Most machines can stretch between 100% and 300%, which is related to the way it is configured. However, 200-250 percent of pre-stretching is used by most people. We know that this is a stable and comfortable running range, and a good balance between economy and efficiency can be achieved.

If an average customer USES five years to pack the film 50 times without prestretching, about $35,000 of film will be wasted. In two years, though, your car pay for themselves the possibility is very small, but, for most people, in less than two years, with the pre-tension fpc3 can pay the cost of the film for themselves.

 

 

Stretch Wrapping

Heating and compression of the resin is the process of extrusion, in the event of the melt, at the right temperature, they push it into a mold, so, continuous plastic layer will be formed.

Stretch film.

The thick layer of the blown film squeezes the film, leaving a circular dead and the air blowing in the air. The limit thickness of the material is determined by the volume of the bubble and the original diameter and thickness of the extruded tube.

How big is the vertical bubble? It is very big, I think there may be many feet high, the effect is a can let the film gradually cooled down, because it always can be rolled up the drum, the bursting of the bubble is because it is done, and the thin, flat membrane tube can be controlled by it, can be controlled by it because it is round.

Usually during the upwind, the edge is cut open, the roll is torn open in width, and wound together when the film is extruded.

This is a vertical process, as shown in the figure.

It is estimated that about 20-30% of the stretch film made today has been blown away.

What is cast iron stretch film.

A different process was involved in the production of the film. In this case, the resin is extruded, also through a linear mold, and then it oozes out, in general, to the large diameter cooling roll. It’s worth noting that, in fact, they may not be cold, but compared to semi-molten plastic, it’s much colder. We according to the extrusion of the original thickness, sometimes thin film can be diluted, dilution of the film will be the target, the instrument by winding the film and it is in comparison with the speed of extrusion, by winding the film faster.

 

The Pre-tension

 

How much stretching should you stretch? Does it stretch as much as possible?

In 1972, PL invented the first elastic packaging, and 60 rolls of plastic film were used by him, using these plastic films for dry-cleaning equipment. The film is placed on the tray of the idea, it relies on is a core of the brake, the purpose is to slow the speed of membrane, make its stretched a little bit longer, and will load compressed into a result is its goal. The invention went viral and evolved into today’s popular fpc1 packaging. Now, we rely on the fpc2 stretch membrane, and this fpc2 stretch membrane is quickly applied.

Process from their point of view, this is basically the same, need to be repeated thousands of times every day, because the workers need to use 12 and 18 inches wide hand stretch film, this hand stretch film is used to package weight.

Load safety is the most important thing that is determined by the capacity of the envelope, which is what we call the envelope force fpc3 film layer. As proven, stretching is not simply a factor.

Dollars and cents.

We all know that stretching a movie is actually an economic measure, or it has a more accurate way of saying that you can stretch a film before a movie is released, which is also an economic measure. The pretensioning membrane is also a stretch film, which can afford to stretch the film, and the stretch film and stretch film industry we know today are also being opened together.

The pretensioning membrane is used to save money.

A: do you know the percentage of pretensioning? Typically, a set of gears before packaging is determined by a common pretensioning percentage, which ranges from 150 to 300%. We can see that every foot of a roll of film, the film on the load is 2.5 to 4 feet.

Stretch Film

The size of the film has been reduced or pre-stretched has increased impact on package force, control, throughput and film costs.

We all know that stretching is an economic measure, or, more accurately, that it is an economic measure to stretch a film before it is released. A stretch film that can be affordable is the pre-tensioning membrane, and the stretch film and stretch film industry we know today are also opened.

The pre-tensioning film can achieve the goal of saving money.

In 100% of pre-stretching, for example, has carried on the increase of the 6000 – foot – long film, into a 12000 feet, in the top 200% of the tensile, the same 6000 feet of film has changed, become 18000 feet, and so on.

In most stretch packs, pre-stretching is standard. According to their configuration, pre-stretching between 100 and 300% of the movie can be done. However, between 200 and 250% is the proportion of most companies. This has been achieved with good balance between economy and efficiency.

In the absence of pre-stretching, an average customer would need to be used for 50 times over five years, and about $35,000 of film was wasted. Although your car may not pay for themselves within two years is what we all know, however, for many companies, if it is a has a pre-stretching fpc1 stretch wrapper, in less than two years’ time, you can pay for the movie alone.

What is the best way to determine best picture usage? Such as:

Load criteria need to be built: they include control values, load to pallet keys, not long or drag-down film backs. They maximize the possibility of safe shipment. We can determine Settings: the quality, specifications, the prices are the choice of film, the adjustment of the machine, the pre-tension percentage, parcel force, at the top and bottom of the package count, film transfer system speed up and down, the film overlap, and so on all need to be adjusted, ensure that reach the standard is our goal.

 

 

Pallet Wrapping

The link below is a link to a suggested chart that will help you find the right deterrent.

To achieve effective and efficient packaging mode is our goal, in order to achieve this goal, we need the film with the least amount of time to achieve the purpose of the right amount of packaging containers, in the stretch wrapper setup, in fact there are still a lot of choice. In the envelope force, the film and film delivery system speed is all right. Different types of stretch films, gauges and pre-stretching levels can be selected. But, we can see the interaction between all these variables are not always obvious, if only one is changed by you, then you will need to adjust another is that you have to do.

What determines its success is the minimal control of the load. The minimum value of a load is not important, and when it is too low, it greatly increases the risk of failure.

The second is the balance between the film layer and the throughput.

In general, there are correct recipes, proper gauges and proper pre-stretching for your load optimization. After these factors are aligned, let you know exactly what the amount of film required for each load is the “cut and weigh” process. We all know that this is a very important distinction because if it’s something that looks shiny, it doesn’t always have to be the specification of the containment at the time of packaging. When the packaging optimization process is completed, a big problem is throughput, which makes a big difference in the table.

One temptation for many large capacity operations is to reduce the number of thin-film layers to improve throughput. If we adjust the film’s performance, thickness and film type, the film layer may be reduced and throughput increased.

 

Stretch Your Load

pallet wrapping, stretch film
Before you buy a machine, it’s important to figure out how to stretch your load.
The transport loss caused by load is the biggest cost driver in the tensile packaging. Fpc1 is the best way to stretch plastic wrap. Manual packing tray, in fact, some of the problems have been we discussed, moreover, usually the manual packing machine is the biggest problem with people on the packaging for packaging, compared to better, faster.
However, machines are also capable, and they are not as smart as you are. There are things they can’t decide:
Have you ever wondered if your favorite movie is working?
The film used for hand wrapping is not good on the machine, and it can be very likely to happen. Film specifications, pre-stretching and materials must be considered by you. Talking to the dealer in your area is something you need to do, and he knows the same thing about the machine as it does with his movies.
Do you know how tight your load is?
The correct containment is required by the top, middle and bottom of your load, which is the tension of the membrane times the number of films. The thing that puts the load together is the containment force. Determining the correct number of containers is the load type of the wrapper. Do you know if your load is heavy, light, or unstable? More control may be required for heavy loads, but it may also require less light load.
What should be a packing pattern?
The Settings of your retractable packaging determine how the load is packaged. The top and bottom packages need to be selected by you. Parcel force Settings must also be to you, and how much you want to load at the top of the use of coating, film transfer system of speed and the rotation of the rotary arm or packaging, all of these need to be to you. What is the cause of the film’s bad?

 semi-Automatic Stretch Wrapping

Today’s semi-automatic stretch wrapping can include more pre-stretching
This is a labor-saving feature that can save you a lot of money. What can you do with the stretch wrap?
First, you can automatically cut the film at the end of the work.
After each cycle, your operator may not leave the forklift or tray. By eliminating this process, 30 seconds of work can be saved, or you can save $7,500 in five years.
Second, the film is captured at the end of the packaging cycle, and the line cycle can be activated without removing the forklift, and the film will be fixed on the load.
The need to cut the film at the end of the loop is not only eliminated, but the need to press the “start” button on the control panel has also been eliminated. Instead, your operators can stay on the forklift, the remote control to start the machine can be used, when the load for packaging, can also perform another task, and extract it can be completed in the cycle. We call this simple automation — it’s a technology that, in the first five years, at least $25,000 has been saved for typical users.
Thirdly, the project can achieve the purpose of weighing the load without increasing the cycle time.
Some stretched wrapping paper is marked on the turntable. When weighing and packing simultaneously, double the load of 30 seconds to 1.5 minutes from a stretch wrapper to an independent flat scale is something you can do. This will reduce the workforce of $7,000 to $15,000 in five years. Also, when you weigh your load each time, the risk of paying a lower fee than the truck’s weight is greatly reduced.
These features have reduced the lifetime of thousands of dollars in human life, and the excellent fpc3 has been provided. Even if they are in the 40 load/day applications, only 20% of the time is used, but they still have great economic significance.

Stretch Wrapping

We can use fpc1 to reduce the cost.
We’re just starting to look like the stretch wrapping might look like a luxury, and some people might think it’s “need” rather than “need.” Those who don’t think it’s necessary may be people who don’t need to wrap their hands all day. What they don’t understand is that machines can pay for themselves in a variety of ways.
Labor.
Valuable time can be vacated by automation, allowing people to engage in other tasks that require critical thinking. And productivity function can also be increased a lot, for example, additional and automatic cutting film, for example, you will be the machine configuration to the degree of automation of you want is allowed, it is not possible before.
Thin film.
Different degrees of pre-stretching are provided by modern film delivery systems. Pre-stretching can increase production per volume, and your consumables can be saved a lot. For example, 200 percent of pre-stretching can change the film, which can turn 6,000 feet of film into 18,000 feet.
Let’s look at the damage.
Hidden is the cost of loss, because the topic is a topic that most of us want to avoid. The truth is that damage can happen, and, in a way, it’s too powerful to ignore the harm that this damage does.
In 2008, a joint study was published by the food and grocery manufacturers’ association (GMA), the food marketing research institute (FMI) and Deloitte Consulting, and the underlying causes of the non-sale products were also discovered. According to the survey, 05% of the products that can’t be sold are caused by damage.
If, now you have 30 pieces of goods on hand, need to ship 1 million dollars a year in the product, so, in five years, $41715 can be saved, you switch to a machine automatic cutting film is what you only need to do, and there are 200% of the pre-tension.

stretch wrappers

A dynamic pre-stretched film delivery system can reduce film costs by at least 50 percent. The process of extending the membrane is pre-stretching and the production of the membrane can be improved. When two rollers rotate at two different speeds in the movie delivery system, they can also cause the film to stretch. An average customer can save a lot of money in 10 years, or at least $50,000 in savings.
A conveyor belt system can help avoid bottlenecks, especially if you plan to pack a load immediately after the next load. After we packed a load, it was pushed to the fpc3 conveyor. What the forklift operator can now do is place another load on the turntable, while the moving load is not needed. About 30 seconds of work can be saved by an average customer, never having to double it, which is the same as about $15,000 in seven years. Furthermore, it is possible to add a feeder to some stretching packages.
The fpc6 wrapper for the built-in scale can be used, and it can scale from a stretcher wrapper to a platform scale for a dual processing load of 30 seconds to 1.5 minutes. A typical user’s seven years of labor savings are the same as $11,000 to $25,000. If you always be you know the weight of the load, pay less than the weight of the truck (LTL) to weigh the costs can be avoided, you use smartphone applications to control weight index and weight information can be stored, and leave the forklift is not needed.
While some functions may result in an increase in the price of a stretched pack, in the long run, the price difference is hardly noticeable. In its economic life, because the cost of productivity has been increased, it can improve the quality of thousands of goods, thus reducing the cost of packaging. If you invest $2,000, productivity increases, and in 10 years, your cost per load will change, and it will cost less than 2 cents.
That’s easy. Investing on a machine, we can all see the benefits of its functionality.
