Thermal shrink wrap is one of the most important things in industries. In the world of industries and manufacturing, thermal packaging comes as an innovative and effective solution to maintain and secure the quality of products during the distribution and marketing process. Thermal packaging is not just a method of packaging products, but rather a technology that ensures that the products are preserved and presented in excellent condition to customers.

Heat shrink wrap is an industrial process used to wrap products with an adhesive plastic layer that protects them from external factors such as: humidity and dust, where:
- This process is carried out using special machines that heat the plastic to a specific temperature so that it adheres tightly to the product.
- Thermal shrink wrap is widely used in many industries such as: Food, beverage, pharmaceutical, electronics, etc. industry.
- It helps protect products and extend their shelf life. It also gives it an attractive and easily recognizable appearance.
- Thermal packaging is characterized by ease of storage and transportation of the products wrapped in it. It prevents it from being damaged or dropped during shipping and distribution operations.
- From our Oleatra factory, we offer many types of thermal shrink wraps.
Handmade shrink wrap
In certain cases it may not be possible or practical to use industrial thermal packaging machines, Therefore, manual shrink wrap is the solution and we offer you…
Our Factory Oleatra Method:
- Manual shrink wrapping method can be used, In this method, the product is wrapped in a flexible plastic wrap that is specially designed to shrink when exposed to heat.
- The plastic wrap is then heated using a hair dryer or manual heat gun to the appropriate temperature until it adheres tightly around the product.
- This manual process requires skill and care. You must ensure that all parts of the product are covered with plastic wrap and that the heat is distributed evenly
To ensure that the wrapper shrinks in an even manner. - Although it is slower than automated methods, manual shrink wrapping is useful for small quantities or products with strange shapes that may not fit together.
With automatic packaging machines.

Shrink bags
Shrink bags are a commonly used material in thermal packaging operations. They are:
- They are made of special plastic polymers that are able to shrink or contract when exposed to high temperatures.
- Shrink bags are flexible and can adhere tightly around products when heated.
- Shrink bags come in different sizes and shapes to suit diverse packaging requirements.
- There are flat bags open on one side, into which the product is placed before heating. Another is closed on all sides, and the product is inserted through a small opening.
- There are also bags with tubular or conical shapes depending on the nature of the product to be packaged.
- Thanks to their distinctive properties, shrink bags are used in packaging many products such as: Food, beverages, medicines, electronic devices, etc.,
To protect it from damage during storage and transportation.
What is a shrink wrap?
Shrink is a thermal packaging process that uses flexible plastic wrappers or bags made from polymers capable of contracting or contracting when heated. where:
- The principle of shrink wrap work is based on the use of plastic wrappers or bags made of specialized polymeric materials that have the ability to expand and contract.
Depending on the temperature. - First the product is wrapped in expanded shrink wrap or inserted into a large shrink bag made of this special material.
- The plastic wrap or bag is then heated by ovens or special heating machines to a specific temperature.
- The polymeric material shrinks and shrinks at this temperature, which leads to it sticking tightly around the product and covering it in a safe and attractive way.
- Shrink technology is distinguished by its durability and its ability to protect products from environmental factors such as moisture and dust. In addition to being easy to store and transport,
So it is widely used in packaging of food, beverage, medicine, electronics, etc.

Is there thermoplastic?
There is a special type of plastic known as thermoplastic or thermoshrink polymers. Thermoplastic is:
- A special polymeric material designed to expand and contract depending on temperature.
- During the manufacturing process, these polymers are exposed to high temperatures and pressure that cause them to temporarily expand or swell.
- When this thermoplastic material is cooled, It maintains its temporary expanded shape.
- But when it is reheated to a specific temperature, They return to their normal state and shrink significantly, forming a tight, adherent shell
around any object encased in it. - Thermoplastic shrinkage polymers are used in the manufacture of thermal packaging (shrink) films and bags. It provides strong protection for products
Against moisture and shocks during transportation and storage.

What are the advantages of using thermal shrink wrap technology?
Thermal shrink wrap technology has many advantages, Of which: Provide strong protection for products against environmental factors such as moisture, dust and shock,
In addition to giving the product an attractive and clean appearance, It also facilitates storage and transportation due to the shrinkage of the packaging around the products. Which saves less space.
What types of plastic are used in thermal shrink wrap?
Special plastic polymers capable of expanding and contracting depending on temperature are used in the manufacture of thermal packaging shrink wraps and bags.
What types of machines are used in thermal shrink wrapping operations?
There are several types of machines dedicated to packaging products using thermal shrink technology. Including electric or steam heating furnaces
Plastic wrap is heated to cause shrinkage. And machines for wrapping shrink wrap around products automatically, Small manual heating devices are used
For small quantities or products with odd shapes.
In the end, thermal shrink wrap technology is considered a modern and effective technology in the field of preserving and protecting various products during storage and transportation operations. Thermoplastic wraps and bags made from shrink polymers provide a safe barrier against harmful environmental factors such as moisture, dust and shock. In addition to providing protection, the thermal packaging process gives the products an attractive and modern appearance. This makes it more attractive to consumers and facilitates the marketing process.
