Stretch Film also known as Plastic Wrap is an elastic and highly stretchable plastic film that is wrapped around goods. It is also this elastic recovery that keeps goods tightly bound and protected. As demands for increased throughput rises, it is particularly important that the cartons stay on the pallet.
When used with pallets, Stretch Film can have several functions:-
Mini or Baby Stretch Film binds your products together without sticking to them.
It’s easy to remove and it will not damage your products.
Commonly used for Wire, Pipes, mirror or glass manufacturers and converters, stationary, DIY, home décor and general usage.
The stretch film dispensers often have a braking system to help obtain a tighter stretch when applying the film.
Hand Roll Stretch Film mainly used in palletizing, bundling of huge or small parcels, luggage, glasses or fragile items, cartons and various application such as Logistic, Warehousing, Factory, Airport & etc.
Machine roll Stretch Film requires a specific Palletizer wrapping machine to complete the job, with minimum work force involved and help reduce waste and increase efficiency. Machine stretch film will also help all loads to be consistently wrapped with the same tension. This helps to improve load security. A heavier film will be loaded to the wrapping machine turn table and pre-set to a perfect finishing.
Color stretch film is a great option for a variety of load shipments. There have multiple reasons to use colored stretch film. Some use for conceal product loads. Having multiple colors to wrap multiple product loads enable quick and easy identification when wrapping.
The answer is No!
People in the industry will know what you mean contextually if you say ‘shrink film‘? But in industry speak that’s actually a specific term for a different kind of plastic – the sort that you might find wrapped around a candle or instant cup noodle. Shrink film is sealed around a retail package and then passed through a heat tunnel which triggers chemical behavior that causes the film to collapse around the package.
2) The heavier film, film length will be longer & can wrap more?
The answer is wrong!
We can’t determine film length or price base on film gross weight. The length will be difference base on film micron and also according the weight of paper core used. The core heavier, the film will be lesser. We suggest check with supplier the net film weight.
3) How to determine stretch film length per roll?
First, we need to find out the net film weight
The formula is Gross Weight – Core weight = to net film weight
The formula to determine stretch film length is
Net Film Weight ÷ Film Width ÷ film thickness ÷ 0.912 (Density g/cm3)
Example: The Net film weight is 2kg, Film width is 0.5 meter, and thickness is 23 micron
2kg ÷ 0.5m ÷ 0.023m ÷ 0.912
The film length per roll = 191 meter
4) How to save money on stretch film costs?
Companies wrapping multiple pallets per day or week can often spend a small fortune on stretch wrap costs throughout the year. In many instances, companies have opportunities to save money by doing a couple things: Purchasing in down gauging or change to Pre-stretch stretch film. Let’s look at these options and how they can potentially save your business thousands in costs throughout the year.
By down gauging companies can save a tremendous amount of money per pallet. In the chart below we take the same films at pallet pricing (60 rolls) to see the cost per wrapped pallet. **All stretch film prices as at Sep 2017**
Pallet dimension is 1.2m X 1.2m X 1.65m (H)
There are 3 type of thickness with same stretch film weight 10kg
23 micron stretch film 1 roll can wrapped 15.5 pallets & cost per pallet is RM5. 24
17 micron stretch film 1 roll can wrapped 21 pallets & cost per pallet is RM3.92
12 micron stretch film 1 roll can wrapped 30 pallets & cost per pallet is RM2.93
The unique and smooth consistency of the film makes it the best and ideal wrapping material.
Another quality to be noted is its tendency to tighten and protect the items, which is found more in the pre stretched film, rather than the traditional wrap.
Common pre-stretch percentages range from 150-300% (Which are typically determined by a set of gears in a wrappers pre-stretch carriage). That means that every meter of film coming off a roll represents 2.5 to 4 meter of film on the load.

Pallet is a flat transport structure that supports goods in a stable fashion while being lifted by a forklift or pallet jack.
Benefit of pallet:-
Pallets are made from various types of materials. The wood pallet dominates the marketplace, followed by plastic pallets, Compress wood pallet, paper pallets, and metal pallets.
Wooden pallets can be found in various designs. In general, wooden pallets are used for heavier products in a one-way flow. Untreated wood are not compliant with ISPM 15. Due to the International Plant Protection Convention (abbreviated IPPC), most pallets shipped across national borders must be made of materials that are incapable of being a carrier of invasive species of insects and plant diseases.
The standards for these pallets are specified in ISPM 15.
To be compliant the pallets must meet debarked standards, and must be treated by either of the following means under the supervision of an approved agency:-
Pallets such as Plastic, compressed wood, paper & metal pallet do not need IPPC approval, and are considered to be exempt from ISPM 15 regulations.
The vast majority of plastic pallets are made from HDPE (high density polyethylene) and PP (polypropylene). The distinction between virgin resins and recycled resins is immensely important. Virgin resins are typically more durable on the molecular level than recycled resins, and they perform better when put through the correct design and processes. Plastic pallets are a complying with ISPM15, it stable and safe packaging solution for all transport applications and can be reused numerous times, and resist weathering, rot, chemicals and corrosion.
Compressed wood pallets or Press wood pallets are moulded through high temperature and pressure processes into one solid piece from dried wood fibres. Compressed wood pallets are recognized worldwide as complying with ISPM 15 No risk of injury from nails or screws. Easily stackable and nest able highly suited to exports and for use as air freight.
Paper Pallets:– Paper pallets, also referred to as “Eco pallets”, are often used for light loads. Paper pallets are also used where recycling and easy disposal is important. Paper pallet are cleaner, safer, and lighter and provide a cost-saving eco-friendly alternative to other pallet materials.
Metal pallets are usually used for transporting heavy goods,
for air-freight, at-sea storage and long-term outdoor storage. Metal pallet are durable, strength & good for sanitation.
