Self Adhesive Bags: Peel-and-Seal Polyethylene Bags for Secure, Professional Closure
When a package needs to be sealed cleanly, quickly, and securely without heat-sealing equipment, tape, or staples, a self adhesive bag provides the ideal solution. The integrated adhesive strip—protected by a peel-off release liner until the moment of use—allows the user to seal the bag with a single press of the fingers, creating a tamper-evident closure that signals professionalism and security. Peel and seal bags are widely used across textile packaging, e-commerce fulfilment, stationery distribution, promotional material dispatch, and any application where manual sealing speed and closure quality are critical operational requirements.
Aydoğan Plastik manufactures polyethylene-based adhesive closure bag products with precision-applied adhesive strips that deliver consistent bond strength across every bag in the production run. Our film extrusion lines produce films in the clarity, thickness, and surface configurations that resealable poly bag and sticky strip pouch applications demand, while our cutting lines integrate adhesive strip application into the bag-forming process for seamless, high-speed production.
Applications Across Industries
Textile and Garment Packaging
Clothing manufacturers and fashion brands use self adhesive bags as the primary inner packaging for individual garments—folded shirts, rolled socks, packaged underwear, and accessory items are placed into clear or frosted PE bags and sealed with the adhesive strip before being packed into outer shipping cartons. The transparent film showcases the garment’s colour and fold quality, while the adhesive seal keeps the bag closed through handling, warehouse storage, and retail shelf display. This application represents one of the highest-volume use cases for self adhesive bags in the global flexible packaging market.
For fashion e-commerce operations, self adhesive bags provide the polished, professional presentation that direct-to-consumer brands need to create positive unboxing experiences. Each garment arrives in its own sealed bag—clean, wrinkle-protected, and ready to wear or display—elevating the perceived quality of the purchase before the customer even touches the product.
E-Commerce Fulfilment
Fulfilment centres processing hundreds or thousands of orders per day value the speed and simplicity of peel-and-seal closure. Unlike heat-sealed bags that require sealing equipment and operator training, self adhesive bags can be sealed by hand in under two seconds—peel the liner, fold the flap, press to seal. This speed advantage compounds across high-volume fulfilment operations, reducing per-order packing time and labour cost while maintaining consistent closure quality regardless of operator skill level.
Multi-item orders benefit from a range of bag sizes within the self adhesive format, allowing fulfilment workers to select the appropriate bag for each product without switching between different closure systems. Our production lines deliver consistent adhesive performance across the full size range, from small accessory bags (10×15 cm) to large garment bags (40×60 cm).
Stationery, Print and Document Packaging
Greeting cards, invitations, photographs, certificates, and printed marketing materials are packaged in crystal-clear self adhesive bags that showcase the printed content while protecting it from fingerprints, moisture, and handling damage. The adhesive closure provides tamper evidence that signals the contents are new and untouched—an important perception for gift cards, collectible prints, and premium stationery items where presentation quality influences purchasing decisions.
Food-Adjacent and Promotional Use
While not intended for direct food contact in most configurations, self adhesive bags are widely used for packaging food-adjacent items: recipe cards included with meal kits, promotional flyers inserted into food delivery bags, sample sachets bundled with retail food products, and display cards for food packaging accessories. Clear PE films with food-contact-grade adhesive formulations are available for applications where the adhesive may come into proximity with food items.
Industrial and Component Packaging
Small parts, hardware components, electronic accessories, and spare-part kits are packaged in self adhesive bags for inventory organisation, retail display, and shipping protection. The clear film allows visual identification of contents without opening the bag, streamlining warehouse picking, quality inspection, and customer receiving processes. Anti-static film formulations are available for electronic component packaging where electrostatic discharge protection is required.
Technical Specifications
Film Thickness and Material
Self adhesive bag films range from 25 to 70 microns. Lightweight garment and stationery bags use 25–40 microns, standard e-commerce and textile bags 40–55 microns, and heavy-duty industrial component bags 55–70 microns. Our co-extrusion lines produce multi-layer structures where the outer layer delivers optical clarity and print adhesion, the core layer provides tensile strength, and the inner layer ensures smooth product insertion and consistent adhesive-strip bonding at the flap closure zone.
LDPE provides softness and clarity for garment and stationery applications, while LLDPE blends add puncture resistance for bags containing items with sharp edges or irregular shapes. Crystal-clear OPP-grade clarity is achievable through optimised blown-film processing parameters.
Adhesive Strip Technology
The adhesive strip is applied to the bag’s closure flap during the cutting process. A silicone-coated release liner protects the adhesive surface until the user peels it away at the moment of sealing. Adhesive options include permanent bond (tamper-evident, non-reopenable) and removable bond (allows the bag to be opened and resealed multiple times). Permanent adhesives are standard for shipping and retail applications; removable adhesives suit applications where bag contents are accessed repeatedly, such as component storage and wardrobe organisation. This versatile self seal packaging approach eliminates the need for tape, staples, or heat-sealing equipment, streamlining packing workflows across both manual and semi-automated operations.
Quality control testing verifies adhesive peel force, tack, and ageing stability on every production batch. Adhesive performance is tested across the temperature range encountered in typical storage and shipping environments to ensure reliable sealing in both warm and cold conditions.
Bag Dimensions and Flap Configuration
Standard self adhesive bag sizes range from 10×15 cm for small accessories to 50×70 cm for large garments and documents. The closure flap—typically 3–5 cm deep—folds over the bag opening and is pressed against the adhesive strip to create the seal. Flap depth and adhesive strip width are calibrated to each bag size for optimal sealing ergonomics and closure strength. Custom dimensions are available subject to minimum order quantities.
Printing and Branding
Up to 8-colour flexo printing adds brand logos, product information, and handling instructions to self adhesive bags. Printing on the bag body is standard; printing on the closure flap is also possible for additional branding. Our graphic design team provides mockups showing adhesive strip and flap fold positions relative to the print design. Lamination adds premium finishes for luxury brand applications.
Production Process
Our integrated facility manages the complete workflow: extrusion, printing, slitting, and cutting with inline adhesive strip application. Every batch passes quality control checks for clarity, adhesive peel force, seal strength, and dimensional accuracy. Production waste is recycled via our recycling facility. Products ship from warehousing and shipping. Visit about us or contact us for samples and project pricing.
