Transparent plastic core stretch film is a type of commercial stretch film used primarily in the wholesale packaging distribution and buying business. This advanced type of packaging film comes in a multitude of diverse types that serve various functional and structural needs in packaging, securing, and bundling products. Below are the most popular types that are often used in different types of applications:
True to its name, a pre-stretched film is already stretched before it is even applied to products. This type of stretched film allows for a tighter and stronger hold since the stretching process sets a specific tension level. It requires less tightening when wrapping products up in packages. The usage of less tightening reduces hand fatigue for workers while providing a consistently tight and secure wrap to the products. Additionally, pre-stretched packaging film uses considerably less film material, providing a cost-saving advantage to those who use it while also being eco-friendly.
This type of stretch film is specifically designed for use with machines and equipment like stretch wrapping machines and automated systems. Stretch wrapping machine film comes in larger rolls that are unwound with a machine to provide a power-wrapped and uniform stretch that is consistent with manual hand-wrapping methods. This film type works best and most efficiently in high-volume packaging environments like warehouses or distribution centers. Furthermore, machine-applied stretch film provides extra strength and security for the products being wrapped up for distribution.
Blown stretch film is manufactured using a blown extrusion process. This film typically has thicker stretches of film gauge than other films. This type of stretch wrap provides excellent puncture resistance qualities along with superior quality. Other than that, blown stretch film also provides clarity of visual points, making it ideal for any application that requires visibility. It is typically used for bundling irregular pallets and products together.
Stretch film Casting is made through a casting process that provides a thinner, lighter stretch film packaging than a blown stretch film. Though the film may be thinner, it still retains strength and comes with a quiet and easy handling advantage. This type of stretch film is favored for bundling and palletizing applications as it effectively keeps stable stacks of products. Additionally, this type of stretch film is particularly suited to packaging lightweight products where the film thickness will not contribute much to its strength.
Transparent plastic core stretch film usually comes with a lot of design variations because of functional and aesthetic value. Here are the most popular and prominent stretch film design variants:
High clarity is a prevalent design attribute for transparent stretch films. This is because clarity helps with product visibility once packaged. High clarity plastic wrap also accommodates marketing strategies and warehouse management practices that require visual assessments of products while still packaged. The clarity design comes from utilizing a thin gauge film that facilitates easier viewing of packaged items.
The core stretch film comes with innovative stretch film features like easy start and easy blend to improve handling efficiency. The easy start design ensures that the film unwinding process occurs smoothly without any film getting stuck or tangled unintentionally. Easy blend designs include adhesive (which acts on the film’s inner surface to bond overlapping layers) so that wraps will securely stick to themselves, hence making application simple and quick. These features significantly impact improving stretch film productivity in the packaging process.
The stretch films are designed to be user-friendly. Manufacturers make stretch films in rolls that can be cut to size and length to suit individual packager needs. Such flexibility allows for economic efficiency because minimal wastage occurs during use. Custom-sized rolls also make applications easier because there is no handling of oversized films that may be cumbersome.
Stretch films also have additional features and design variants, like colored stretch films that offer minimal security and concealment. Colored stretch film can also be used for branding purposes and to provide additional protection from the sun’s radiation, thus extending packaging protection outside the building. This UV protection feature is typical for products that require shading from the sun in order to maintain their integrity and quality. Such a film is especially beneficial for food products, paints, or industrial chemicals that may be damaged due to excessive exposure to sunlight.
When dealing with transparent plastic core stretch films, there are some very important specifications that one has to consider to achieve the desired application and maintain optimum film in order to realize the best optimal functionality:
The thickness of the stretch film generally comes in assorted gauges, usually between 50 and 120. The thickness selection highly depends on the nature, size, and weight of the items that are going to be packaged. Thin films are designed for lightweight products that have a moderate shrink requirement, while thicker films provide superior strength and stretch for heavier or bulkier products.
Pallet stretch film is designed with different load capacities depending on the size and size of the items to be packaged. Additionally, the delivery capacity refers to how much weight the stretch film can support without tearing or stretching out. It also indicates the maximum weight of the packaged products intended for unitized shipping. Choosing appropriate load capacity prevents film failure during the packaging process as well as during delivery.
Stretch film has to be properly maintained for maximum efficiency. This can involve keeping the film in a cool and dry environment, preventing extreme temperatures and humidity from affecting the film’s elasticity and adhesion properties. The application of stretch film can be done using a manual or powered stretch wrapper depending on the packaging environment. Proper tensioning eliminates wastage and ensures safeguarding the products. Films should also be selected according to the requirements of the products being packaged, for example, in terms of stretchability and thickness.
The stretch film core plastiques has multiple applications in diverse industries and settings, with each case requiring different packaging and products handling. Below are some scenarios where this film proves very beneficial:
In the mentioned application, the film is used to stabilize and secure pallet loads during transportation. Proper packaging of the materials prevents shifting, which may cause damage in transit. Core stretch films keep materials contained and protected from dust and moisture. Moreover, the clarity of the film enables the materials to be visually identified, thus eliminating the need for unwrapping them at every stage of handling.
Stretched films are usually employed for bundling, consolidating, or protecting bulk items in manufacturing plants. For example, it can insulate manufactured goods such as machinery and parts from damage during handling and storage. This film is versatile, be it around irregularly shaped products or uniformly shaped ones; it provides exceptional security and protection. This is crucial for maintaining quality standards in the manufacturing industry.
Please pack the products individually using stretch film to provide retail presentation. Commonly available stretch films group or bundle like items together in order to present them neatly on shelves. This is particularly true in the case of smaller items where grouping would facilitate increased handling efficiency and provide a certain degree of security against theft. Additionally, the clarity of the films makes items visible to customers.
Core stretch film is widely used to wrap and protect construction materials such as pallets of wood, sheets of drywall, and tile from weather elements. It is used for securing loads during transportation and keeping materials together on-site. Because of its UV protection capability, it provides enclosing film over items that must be protected from sun exposure to prevent deterioration over time.
In this scenario, the stretch film is employed to secure parcels, boxes, and shipments of various sizes. It comes in handy, especially when a package needs several items to be inside it; thus, the film keeps items together during shipping. This form of protection prevents items from jostling or moving, which would cause them to become damaged or fractured in transit. With e-commerce businesses that ship on a daily basis, this film is very indispensable because it offers a very inexpensive yet highly effective means of safeguarding items.
The advanced paper stretch film has to be carefully selected regarding the requirements of the specific application and the preferences of the users. Below are the few determining factors regarding which those manufacturers can decide which stretch film would be the best for their clients:
Stretch films are manufactured in different thicknesses for different categories of products. Thin films work well for lighter products as they provide moderate levels of wrap-around compression. For heavier and bulkier products, thicker films will be better because of their increased tensile strength. Over-extension of films should not be allowed, as that can compromise the integrity of the film; hence, the thickness that corresponds to the packaged products' weight and size should be chosen.
Core size stretch film is designed with different core sizes, generally 1 inch and 3 inches in diameter. It is of great importance to ensure that the stretch film being used is compatible with the film holder or machine used in the packaging process. For applications that require frequent film changes, core 1-inch size is preferred. In applications with high volume, packaging will need less frequent changeovers, thus prefer a 3-inch core size.
The stretch ratio represents how far the film can be stretched without breaking. A good stretch ratio allows the film to conform tightly to products while ensuring maximum use efficiency. Cases where the film is exposed to sharp edges or irregular surfaces demand high puncture resistance. Puncture resistance means the film will not tear in such exposures, which will leave the products exposed to hazards and therefore have no protection.
Tensile strength is the measure of the film's ability to stretch under tension and still keep integrity. Higher tensile strength is better for applications where the load will be subjected to pull forces, such as during transportation. In such cases, load stability is crucial, and films with high tensile strength are preferred. Always match tensile strength to the specific needs of the wrapped product to strike a balance between flexibility and strength.
Stretch films are either opaque or high-clarity types. High-clarity films allow visual inspection of wrapped products, which is essential in warehouse management and retail applications. Core stretch films with opaque designs are used where product concealment or security is desired. The clarity type of film also comes with added levels of protection and tampering.
