The Strapping Belt is one of

the most commonly used means of unitization and bundling in the packaging industry.

There are multiple types of strapping products available, as well as many application

types, but strapping is especially used in environments such as:
Bundling together for handling and shipping: newspapers, pipe, lumber,

concrete block, etc.
Attaching items to pallets, skids, and crates
Reinforcing wooden boxes, crates, and corrugated boxes, such as Gaylord
Attaching items to flatcars, flatbed tractor trailers, etc.
Strapping is most often used in complete horizontal or vertical bands.

Typically, edge protectors are used to help spread the strap’s tension on the load

at corners and reduce damage caused by that tension. Strapping can also be used in

loops attached to holding locations such as rail cars, tractor trailers, or skids.
Main types of strapping available
Steel strapping: steel is the oldest, strongest, and highest tensile strength

strapping available. It is available in a variety of widths and thicknesses, as well

as variations in the grade of steel. Steel is used for heavy duty holding where high

strength and minimal stretch are desired, as well as when the product may be sharp or

hot.
Plastic strapping: Polypropylene and polyester strapping are the main types of

plastic strapping today. PP

Strapping is an economical material designed for light to medium duty

unitizing, palletizing, and bundling. It is available in various widths, thicknesses,

and polymer variations (e.g., copolymers). This product offers higher elongation but

tends to have irrecoverable dead stretch with constant stress. Polyester strapping is

the most rigid option, offering the strongest plastic strapping, and is used as a

viable alternative to steel in many industries. Polyester provides excellent retained

tension on rigid loads and its excellent recovery properties help a load absorb

impact without strap breakage. It has significantly less elongation than

polypropylene and retains tension over a longer period of time.
Polypropylene strap is typically embossed, feels more like plastic, and

has a matte-style finish.
Polyester is a glossy, smooth strap; it does not resemble polyester

fabric in any way.
Since polypropylene is the most common plastic strap option, the term

“poly strapping” will generally refer to polypropylene.
Polyester Composite Strapping works best when you need higher

initial tension; polypropylene is best when high initial tension is unimportant and

only low retained tension is needed.
Because of its long history in the packaging world, there are lots of different

types of strapping today; however, most strap is made from either steel or plastic.

Each has their own advantages and disadvantages, making it critical to figure out

exactly what works for your specific needs.
Which stretch film do you use for which load?
Often only a distinction is made between light, medium and heavy loads. In our

experience, however, there are several factors that need to be taken into account. An

important question, for example, is whether a load already has a certain stability or

not.
For instance a pallet with toilet paper and a pallet with bottles of soft drinks.

The former itself has much less stability than the latter. Another important factor

is the wrapping machine that is used; what is the stretchability and what is the

speed.
Sometimes the speed of the wrapping process can demand a thicker

Stretch Film in order to guarantee

the high output. Many factors play a role in choosing the right type of stretch film.

What is an Adhesive Tape?
Pressure-sensitive Adhesive Tape

s consist of a backing material film coated with an adhesive intended for

relatively low-stress applications. Light pressure, usually done by the fingertips,

is applied to initiate the binding. In the sticking process, the fluid properties of

the pressure-sensitive adhesive change rapidly to flow and set in the surface of the

substrate.
Adhesive tapes first appeared in the mid-19th century for medical applications.

In 1845, Dr. Horace Day created bandages from strips of fabric with rubber adhesive

tapes. It was the inspiration behind Johnson and Johnson‘s Band-Aid. In 1923, the 3M

Company formulated the first masking tapes. Adhesive tapes kept on evolving to

materialize the present varieties of adhesive tapes (e.g., packing tape, painter‘s

tape, and electrical tape) which serve their unique application. Nowadays, adhesive

BOPP Tapes are certainly

found in most offices, households, shops, and industries which undoubtedly makes them

one of the most useful tools ever invented.
Adhesive tapes are efficient and readily available to perform different functions

such as joining, masking, sealing, splicing, bundling, and surface protection, which

does not require machinery or any other special tools. Adhesive tapes are lightweight

and efficient to store; it usually comes in rolls and is only unwound if there is a

need for adhesive. Unlike the traditional mechanical fastening objects such as screws

and bolts, it eliminates the need to pierce or punch the substrate which induces a

stress area.
Iron packing buckle: The iron

Packaging Buckle must be packaged with a special packing machine and a special

plastic packing belt. Use special strip steel and special tinplate. There are dense

small thorns in the packing steel mouth, which has the effect of anti-skid,

increasing the tension of the contact and ensuring the safety of the goods.
Strapping Machines are

packaging machines that use bands of flat steel or plastic tightened around a package

or pallet of goods and fasten together to secure the package. Straps can bundle

products together, improve containment strength and to secure a load to a shipping

pallet. Straps are made from a variety of materials based on the required strength of

the strap.
