Technical terms, product types, and production details used in the packaging world can sometimes be confusing. At Vakumpak, we have prepared this comprehensive glossary to eliminate misinformation in the industry and provide a clearer experience for our customers and visitors. Whether you are interested in packaging technologies, planning to have production done, or simply curious, you are in the right place.
Packaging is not just a protective layer but also a critical factor for the presentation of your product and the first impression it creates. Shaped according to different needs, packaging types directly affect both shelf life and customer experience. In this category, we define the most commonly preferred packaging formats.
Doypack (Stand-Up Pouch)
Widely used in the flexible packaging sector, this functional and aesthetic packaging type stands upright on its own thanks to its gusseted bottom structure. Typically produced with multi-layer lamination technology, it provides barrier properties (against oxygen, moisture, light, etc.) that extend the product’s shelf life.
Gusseted Pouch
A special type of packaging with flexible, foldable gussets on the sides that expand volumetrically. Usually made from paper, plastic, or composite materials, these pouches adapt to the volume of the product, making them convenient to use and easy to transport.
Vacuum Packaging
A packaging method based on removing the air inside the package with special machines to create a low-oxygen environment, which is then sealed tightly.
Shipping Packaging
Designed to ensure safe, damage-free, and organized transportation of products during logistics processes. Playing a critical role in protecting items from the point of sale to the end-user in e-commerce, retail, manufacturing, and distribution sectors, shipping packages are available in various forms such as kraft bags, bubble mailers, and plastic courier bags.
Stick Pack
An innovative packaging solution developed for single-use products, designed in a long and slim form. Suitable for granules, powders, liquids, or gels, stick packs enable hygienic, practical, and cost-effective packaging.
Gift Packaging (With or Without Adhesive Strip)
Specially designed packaging solutions that provide an aesthetic, elegant, and thoughtful presentation of products. Developed to enhance customer experience and strengthen brand image, these are offered in two main categories: with adhesive strips and without.
Top Film Roll Solution
Top film refers to the roll (reel) format of the foil layer used in multi-layer packaging systems to cover and protect the product. This solution is particularly applied as a sealing material on thermoforming machines, tray seal machines, and vacuum packaging systems.
Flat Bottom Pouch
Increasingly preferred in the flexible packaging industry, as its name suggests, this pouch has a flat and sturdy bottom. This feature allows it to remain upright without support even after being filled.
Ready Packaging
Pre-manufactured packaging produced in specific sizes and standards, continuously available in stock. These options provide the advantages of fast delivery and lower cost since they are kept ready at all times.
Quadro Packaging
A modern type of flexible packaging with four sealed edges in a rectangular prism form, combining aesthetics and functionality. With its upright stance and neat edges, it is especially preferred for premium products. Produced with multi-layer laminated films, quadro packaging ensures long-lasting freshness with its strong barrier properties.
Sachet Packaging (Three-Side Seal Pouch)
A flexible packaging type commonly used for small-sized, single-use products, sealed on three sides. With its practical use, hygienic structure, and cost-effective production, it is widely preferred in sectors such as food, cosmetics, healthcare, cleaning, and personal care.
Retort Packaging
A type of flexible packaging resistant to high heat and pressure, used especially for food products that require long shelf life through sterilization. This system allows foods to be stored for long periods at room temperature without spoilage or the need for additives.
Back-Seal Packaging
A type of packaging that provides an aesthetic look, high protection, and production efficiency. In this form, the material is shaped into a tube and sealed or heat-welded from the back, with the top and bottom sealed afterward to ensure airtight packaging. Commonly used for powders, granules, and liquids in single or multi-portion packs, it is widely preferred in food, cosmetics, medical, cleaning, and chemical industries.
Packaging material affects many factors such as durability, freshness protection, and visual quality. The layers and raw materials used can be decisive for the shelf performance of your product. In this section, you will find the material types commonly used in the industry.
PET (Polyethylene Terephthalate)
Polyethylene Terephthalate (PET) is a high-performance, durable, and versatile polymer belonging to the thermoplastic polyester family. PET can be used both on its own and as a component of laminated structures in flexible and rigid packaging solutions. It offers high resistance to heat, moisture, and chemicals, making it an ideal packaging material in terms of both shelf life and hygiene.
CPP (Cast Polypropylene)
Widely used in the packaging industry, this type of polypropylene film is produced by the cast process and is known for its high clarity, flexibility, and heat resistance. Particularly in flexible packaging applications, CPP is used either alone or as an inner or outer layer in multi-layer laminates, delivering superior performance in product protection, presentation, and functionality.
Aluminum Lamination
Aluminum lamination is the process of combining aluminum foil with one or more polymer films (such as PET, PE, CPP, etc.) to create multi-layer structures (laminates). This technique is particularly used for products that require critical protection such as high barrier performance, heat resistance, and light impermeability.
PE (Polyethylene)
One of the most widely used thermoplastic polymers in the packaging sector. Available in different types such as low-density (LDPE), high-density (HDPE), and linear low-density (LLDPE), PE is preferred in a wide range of packaging applications thanks to its flexibility, durability, and chemical resistance.
BOPP (Biaxially Oriented Polypropylene)
BOPP, or biaxially oriented polypropylene, is a thermoplastic film that provides high performance and aesthetics in the packaging industry. During production, the polypropylene film is stretched in both machine direction (MD) and transverse direction (TD), giving the film high mechanical strength, clarity, and gloss. Used both on its own and as a layer in laminates, BOPP plays a significant role in product protection and extending shelf life.
Kraft Paper
A paper type frequently preferred in the packaging industry for its high strength and natural appearance, especially in eco-friendly and sustainable packaging solutions. Produced by chemically processing wood pulp, kraft paper’s high tear resistance and durability make it both a protective and aesthetic packaging material.
PLA (Polylactic Acid)
A biodegradable and compostable thermoplastic polymer made from plant-based resources (commonly corn starch or sugarcane). Compared to conventional plastic packaging materials, PLA stands out as an innovative material that reduces carbon footprint, is naturally degradable, and minimizes environmental impact in recycling processes.
Metallized Film
A multifunctional packaging material produced by depositing a thin metal layer (usually aluminum) onto the surface of polymer-based films such as polypropylene (BOPP), polyester (PET), or polyethylene (PE) through vaporization. Metallized film is widely used in the packaging sector to provide an aesthetic look, protective barrier, and product durability.
The print on packaging is like the showcase of a brand. With the right printing technology and an impressive design, it is possible to create trust and appeal in the eyes of consumers. In this section, we explain the printing techniques and design-related terms used in the industry.
Flexographic Printing
A high-speed and cost-effective relief printing technique that uses a rotary system to print on flexible packaging materials. This method works by transferring water-based or solvent-based inks to the surface through rubber or photopolymer plates.
Gravure Printing (Rotogravure)
An industrial deep printing method used to transfer high-quality and detailed images onto packaging materials. In this technique, the image is engraved directly onto a cylinder, with each color requiring a separate gravure cylinder. Ink fills the engraved cells, and excess ink is removed by a doctor blade, leaving only the desired design to be printed.
Matte and Gloss Lamination
Gloss Lamination: Adds high shine to the surface, enhancing visual appeal and creating an eye-catching look. Matte Lamination: Provides a non-reflective, sophisticated, and elegant finish. It is particularly used in premium product packaging to create a modern and refined perception.
Spot Varnish (Selective Varnish) Printing
A special printing technique where gloss or matte varnish is applied only to specific areas of the packaging surface. This highlights elements such as logos, product names, or graphic details, enhancing both the aesthetic and perceptual value of the packaging.
CMYK Printing
A color separation system based on the combination of the four primary colors: Cyan, Magenta, Yellow, and Key/Black. It is used in digital or offset-based printing to create multi-colored and detailed images. In the packaging industry, CMYK printing is widely applied to reproduce graphic designs, brand logos, product visuals, and text with high accuracy and realism on packaging surfaces.
Window Patch Design
A special design application where a specific area of the package is covered with transparent material (usually PET film, OPP film, or acetate) to make the product inside visible. This transparent window builds consumer trust and creates a visual advantage that positively influences purchasing decisions.
Digital Printing
A modern printing technology that transfers designs prepared on a computer directly to the printing machine without requiring plates. In the packaging industry, digital printing is ideal for personalization, short-run production, fast prototyping, and campaign-based custom designs.
Embossing/Debossing
Techniques used to give the packaging surface a three-dimensional effect. Embossing: Raises specific elements (e.g., logo, brand name, graphic patterns, or symbols) above the surface. Debossing: Presses them into the surface. Both methods add a tactile and visual emphasis to the packaging design.
