Definition of Hand and Machine Stretch Film
Hand Stretch Film is a type of plastic film that is used for wrapping, securing, and stabilizing goods. It is widely used in palletizing and unitizing activities to bundle, secure, and stabilize objects for shipping, transportation, or storage. Hand stretch wrap is applied by hand and is stretched when wrapped around a product, creating a tension that holds the film securely in place. It is made from linear low-density polyethylene (LLDPE), which is a stretchable plastic film that provides the superior load-holding force, puncture resistance, and clarity. Hand stretch wrap is a cost-effective and efficient way to package, protect and transport goods.
Machine stretch film is a highly elastic plastic film used to wrap and secure items together. It is wrapped around a pallet or box of items and then stretched and secured with tape or a machine. The film is made from linear low-density polyethylene and is highly elastic, allowing it to stretch up to 200% of its original length. This allows it to conform to the item it is covering and create a tight and secure bond. The film is also water and dust-resistant, helping to keep the items safe from the elements. Stretch wrap machines are an economical and efficient way to wrap and secure items for shipping and storage.
Overview of Hand Stretch Film
Hand stretch film is a type of plastic film used to wrap and secure items for storage or transport. It is frequently referred to as stretch wrap or pallet wrap. Hand stretch films are an economical and efficient way to secure and protect items. The film is applied by hand and stretched over the items to create a tight, secure hold.
It is available in a variety of lengths and widths, as well as different strengths and colors. Hand stretch wrap can be used to wrap and secure pallets, boxes, furniture, and other items for storage or shipping. It also provides a dust and moisture barrier to protect items from the elements.
Overview of Machine Stretch Film
Machine stretch film is a specialized plastic film that is used in many different industries to secure and protect loads. It is made of a polyethylene blend that is stretchable and highly stretchable. The film is used to wrap and secure items onto pallets or other containers, which is an important part of the packing process.
Machine stretch wrap is available in a variety of sizes and thicknesses, and can be applied by hand or with a machine. It is designed to stretch when wrapped around items, providing a secure hold without requiring the use of other binding or securing methods.
Comparison of Hand and Machine Stretch Film
Cost
When it comes to cost, hand stretch film is generally more cost-effective than machine stretch film. Hand stretch film is typically sold in rolls of various lengths and widths and is much less expensive than machine stretch film. However, hand stretch film is labor-intensive and time-consuming to apply, making it more costly in terms of labor and time.
On the other hand, machine stretch wrap is generally more expensive than hand stretch film, but is much faster to apply and requires less labor. Machine stretch wrap also typically provides a more secure wrap than hand stretch film, making it a better choice for securing heavier loads. Additionally, machine stretch wrap can be purchased in longer lengths, which can save money in the long run.
Usability
Hand stretch film is an economical and versatile packaging solution that is easy to use and can be used to securely package a variety of items. The film is applied by hand, usually with a stretch wrap dispenser, and is stretched around items to provide a secure hold. Hand stretch film is cost-effective, fast to apply, and can be used on a variety of items.
Machine stretch film, on the other hand, requires a machine for the application. The machine applies the film quickly and efficiently, which is ideal for larger packaging jobs. As the tension memory of the film can be altered to provide the ideal hold, it is also more secure than hand-stretch film. Machine stretch wrap is more expensive than hand stretch film, and is not suitable for smaller items.
Overall, hand stretch film is usually the best solution for smaller packaging jobs due to its low cost and ease of use. For larger jobs, machine stretch wrap is the better option due to its superior tightness and tension memory.
Efficiency
Hand stretch film rolls of hand stretch film are a great choice for low-volume applications and are frequently used for simple jobs like unitizing and palletizing. Hand stretch films are typically cheaper than machine stretch films, but are less efficient as it requires a manual application. Hand stretch films are more susceptible to user error, and can often result in unevenly applied film, which can lead to damage to the product being packaged.
Machine stretch film, on the other hand, is a more efficient solution for higher-volume applications. Machine stretch films are applied using automated stretch wrappers and can be applied consistently, resulting in more uniform coverage and better protection for the products being packaged. Different to hand stretch films, machine stretch films are more expensive, but the application’s improved dependability and efficiency make up for the difference.
Tensile strength
Hand stretch films are designed for light-duty applications and are less costly than machine stretch films. It offers good tear resistance and a good cling level, but its tensile strength is lower than that of machine stretch film rolls. Cast stretch film typically has a tensile strength of up to 50 pounds per inch and is not designed for heavy loads.
Machine stretch film rolls are made for greater loads and have a higher tensile strength than hand stretch film. It typically provides exceptional rip resistance and cling levels together with a tensile strength of up to 100 pounds per inch. Rolls of machine stretch film are more expensive than hand stretch film and are made for applications that require greater rigor.
Packaging methods
Hand stretch film is a plastic wrap that is applied to packaging to enclosed tightly and safely guard the objects. It’s applied by hand, typically with a dispenser. Cast stretch film is a cost-effective solution for bundling and protecting items and is often used for lighter weight and smaller packages. It’s easy to use and can be quickly applied by hand. However, it is not as durable as pre-stretch film and can be more difficult to apply on larger packages.
Machine stretch film is a plastic wrap that is used in packaging things that should be wrapped safely and secured. It’s applied with a machine, typically a stretch wrapping machine. The pre-stretch film is a more secure and durable solution for bundling and protecting items and is often used for larger and heavier packages. It’s more efficient than hand stretch film and can be quickly applied with a machine. However, it is more expensive than cast film and requires the use of a machine.
Areas of use
When it comes to areas of use, hand stretch film and machine stretch film have their distinct advantages and disadvantages. Hand stretch wraps are a great choice for small to medium-sized packages, as it is easy to use and requires minimal effort to apply. It is also a great choice for irregularly shaped products, as it is simple to use in any shape and size. However, hand-cast stretch film is not as strong or durable as machine stretch wraps, therefore may not be the best choice for larger packages or heavier items.
Machine stretch film on the other hand, is a great choice for larger packages and heavier items, as it offers a much higher level of strength and durability than hand-cast stretch film. It is also a great choice for more consistent and uniform wrapping of packages, as it can be used quickly and efficiently. However, a machine-blown stretch film can be more difficult to accustom for irregularly shaped products, as it may be harder to apply and shape the film to the desired size and shape.
