PVC Shrink Films
Polyvinyl Chloride (PVC) shrink film is one of the most widely used packaging films in various industries due to its high transparency, suitable shrinkage capability, and cost-effectiveness. This film, like other shrink films, shrinks uniformly around the product when heat is applied, creating a safe, aesthetically pleasing, and dust- and moisture-resistant packaging. There is a relative difference between PVC shrink films and other types of shrink films, with its high durability and physical strength being noteworthy.

Types of PVC Shrink Films
PVC Shrink Wrap
This film is the basic form for packaging simple products; for example, it is used for packaging non-food items such as software boxes, CD/DVDs, stationery, and consumer goods. High transparency and rapid shrinkage are its prominent features.
PVC Shrink Sleeve
The sleeve film wraps around bottles and containers and takes the shape of the container when heat is applied. This type of film is used for 360-degree branding, security sealing, and attractive graphic designs in beverage, cosmetics, and pharmaceutical industries.
PVC Shrink Tubing
Shrink tubes are used for packaging long or bundled products like cables, electronic components, and tools. This type of film is produced in tube form and shrinks uniformly around the product when heated.
Features of PVC Shrink Film
High Transparency
PVC shrink film has high light transparency (over 85%) and a glossy surface, which enhances product visibility in packaging. This feature is particularly important for packaging consumer products such as cosmetics and electronics.
Effective Shrinkage at Low Temperatures
This film shrinks at relatively low temperatures (around 110–150 degrees Celsius), resulting in energy savings and increased packaging speed.
Resistance to Moisture and Dust
PVC shrink film effectively protects products from moisture, dust, and environmental contaminants, which is vital in packaging food and pharmaceutical products.
High Printability
The smooth and uniform surface of this film allows for high-quality printing, which is very important for branding and product information.
Application of PVC Shrink Film
Food and Beverage Industry
PVC shrink film is used for packaging bottles, cans, and food containers due to its high transparency and effective shrink-ability. Additionally, its high resistance prevents the passage of bacteria and moisture into the packaging.
Pharmaceuticals and Hygiene Industry
In the packaging of tablets, syrups, and hygiene products, PVC shrink film acts as a safety seal and a protective barrier against contaminants. Its high transparency and printability allow for the inclusion of product information and branding.
Electronics and Software Industry
For packaging CDs/DVDs, accessories, and electronic components, PVC shrink film provides suitable physical and aesthetic protection. This film, with uniform shrinkage and high clarity, protects products from dust and physical damage.
Cosmetics and Personal Care Industry
In the packaging of cosmetic products, perfumes, and creams, PVC shrink film functions as a protective and attractive layer. The clarity and gloss of this film enhance the visual appeal of the product and provide protection against contaminants.
Printing and Publishing Industry
For packaging books, magazines, and stationery, PVC shrink film offers protection against moisture and dust. This film, with uniform shrinkage and high transparency, protects products from physical damage.
Industrial and Construction Industry
In the packaging of industrial equipment, spare parts, and building materials, PVC shrink film serves as a protective layer against moisture, dust, and physical damage. This film, with high resistance and effective shrink-ability, protects products from environmental harm.
