Shrink Wrapping Packaging and Its Importance

Shrink Wrapping Packaging and Its Importance

Despite the size of your business, offering items that have imperative eye-catching packaging should be your target. Proper packaging not only increases income but rather helps you to acquire new clients.  This is possibly why dominant part of organizations has implemented shrink wrap packaging.

Shrink Wrapping process

Shrink wrapping machine uses two things – heat and plastic film. The shrink wrapping packaging entails wrapping an item, of any size or shape, with the plastic film first and then passing the package through heat. Heat causes the plastic film to shrink and to seal the item firmly. Here are the main benefits of shrink wrap Packaging:

Prevalent Durability

Shrink wrap item packaging offers more exceptional sturdiness than some other packaging. The plastic film incorporated in shrink wrap packaging gives the product high strength making it difficult to damage. This makes it ideal for items that require transport, particularly if it’s meant for long distance or overseas.

Enhances Product Protection

Since various items, fundamentally because of size, shape, and configuration, require distinctive care, finding the best packaging is hard. Be that as it may, with shrink wrap packaging a product will be safely bundled and protected. Shrink wrapping completely shields encased things from negative factors such as moisture and dirt that may interfere with the product. The reason is that in shrink wrap packaging shrinks an item firmly.

Cost effective Process

Shrink wrap packaging is relatively budget-friendly contrasted with other packaging choices. Shrink-wrapped items accordingly don’t consume up much room in distribution centers or plants enabling the proprietors to utilize the space for different things. In addition, since shrink wrap item packaging requires less space for capacity, it additionally requires less space in transport what implies more items can be sent without a moment’s delay.

Easy Transportation of Products

Capacity and space inside should be utilized to accommodate many items. In case the packaging material also needs some space then it will end up consuming more space in lorries, flight conveys, and other delivery compartments. Not exclusively is this an insufficient utilization of room, yet it additionally results in significantly higher transportation costs, which thus, prompts a considerably higher fuel utilization. Shrink wrap enables the item to be secured utilizing the absolute minimum of material. Instead of massive boxes or holders, the film in this form of packaging takes up as little room as is conceivable away and amid transportation.


One of the numerous advantages of shrink wrap is that the film used is clear. This implies things, for example, foods grown from the ground that needs light can even be packaged and transported. It also allows the client to check the nature of the item before buying enabling them to guarantee to select the best item. Shrink wrap is likewise massively helpful for showcasing purposes, as the details can be imprinted on the package. Also, this process enables the organization to include critical data on the packaging, while yet empowering the purchaser to see what is inside.

Can Production Line

Can Production Line

Use of tin cans dates back to the World War II; this is where large quantities of beer were shipped to the servicemen overseas. Since then, use of can has been commonly used primarily for filling beverages and selling food products before sale. The initial cans were made of steel but over time aluminum material was incorporated that prevents the galvanic reaction between the product and the can. The manufacturing process of a tin entails several steps that integrate together to form the final item.

Here are the steps involved:

Cutting the Blank

Wall ironing and two-piece drawing is a conventional method of making cans that have been employed by most companies. The first step in the tin can manufacturing process is can maker machine cutting the blanks from the metal plate. Usually, this process begins with aluminum ingot that measures about 30 inches being rolled to form a thin sheet. The next step is to cut the thin sheet into circles called blanks that will make the body and the bottom of the can. During this process, about 12 to 14 percent of the sheet is wasted, but it can be used later as a scrap.

Redrawing the cup

The next step in the can production line is to redraw the cup. The small cup from the initial draw is moved to the second station where a sleeve precisely holds the cup, and the lower end is punched swiftly into the cup. The punch pushes this cup against three iron rings which stretch and thins the cup walls. Drawing and ironing operation happens under continuous punch stroke and takes a short period. Then there is another punch that presses the base of the cup making it bulge inside. The lower walls and the bottom should be made slightly thicker to increase the strength.

Trimming the ears

The process of ironing and drawing can leave a slightly curved at the top. These small ripples called ears that are unavoidable. Trimming is then done at the top end of the can to make the upper walls level and straight.

Cleaning and Decoration

After obtaining a smooth and shiny outer wall, there is no need any other finishing. The can is cleaned and then printed with labels. After this, the can is then decorated, and the upper top is slightly squeezed with the necking machine. Then it is then flanged outward at the top so that it can accommodate the lid.

The Lid

A lid for the base is mostly of different material from the body. The inward bulge made at the bottom will help the can withstand pressure from the products inside. A lid should also be stronger and stiffer. The center of the top is usually stretched upward with a machine to create a rivet. The cans are then checked automatically for any leakages or cracks.

Filling and Seaming

After the can is checked, it is ready to be filled with the desired products. The can is held tightly as the beverage is poured in then the lid is added. The upper flange initially formed is then bent around and sealed.

It is also designed with power press double operation mechanism for folding and locking at the same time. This is a highly accurate machine and it is built for heavy-duty operations.

Materials Used For Making Cans

 Most of the cans are made from tin and aluminum materials. The reason behind the two types of metals is the fact that they are malleable. This implies that the materials can be transformed into various shapes among them, the can shape.

Another factor that is considered is that the two metals are resistant to corrosion and rust as well as being able to be recycled.

Even though the two materials are often used interchangeably, they are in fact different because they possess contrasting properties and have different manufacturing costs.

Tin cans are known to be heavier than those made of aluminum and are more long-lasting. Also, tin cans are highly resistant to the corrosive nature of some foods such as tomatoes. But aluminum cans have one major advantage such that they can be recycled.

The third category of materials can be described based on work-craft. There are flat metal raw materials that are classified according to their thickness.

They may include foil or leaf metal, sheet metal and plate metal. Perfect examples of items derived from work-craft materials are aerosol cans and milk powder cans.

Also, lock seam cans fall in this category of work-craft materials and some of the common items in this group include tea cans, chewing gun cans and many more.

The advantage of using work-craft materials is that it reduces the amount of metal fabrication thus lowering the cost of production drastically.

To wrap up, this tin can making machines are skillfully made to fulfill your desires and needs. They usually undergo vigorous quality tests at every level of their production.

This is done to achieve acceptable standards in terms of precision, abrasion, tensile strength, durability, maintenance and operation.
