Zip Lock Bags

Find the answers you need below. If you have any additional questions, our customer service team is always here to support you.

Question 1: Which zip lock bags are best for food storage and freezer use?
For food storage and freezer use, we recommend our food-grade zip lock bags made from LDPE material, which are specifically designed for safe contact with consumables. Our 90 micron heavy-duty zip bags offer superior protection for freezer storage, as they are more tear-resistant and provide better insulation against freezer burn. The transparent design allows easy content identification, while the secure zipper closure keeps food fresh and prevents freezer odors. All our resealable bags for food applications are 100% recyclable and available immediately from stock with fast shipping to ensure your kitchen storage needs are met promptly.

Question 2: What is the difference between 50 micron and 90 micron zip lock bags?
The primary difference between 50 micron and 90 micron zip lock bags lies in their thickness and durability. 50 micron bags are lightweight resealable bags ideal for general storage of non-heavy items like documents, small parts, or lightweight products in offices and workshops. The 90 micron heavy-duty bags are significantly more robust, offering superior tear resistance and puncture protection for demanding applications such as shipping heavier items, storing sharp objects, or long-term freezer storage. Both thicknesses are manufactured from high-quality LDPE material and feature reliable zipper closures, but the 90 micron version provides enhanced strength for professional and commercial requirements.

Question 3: What sizes of resealable bags are available at karton.eu?
Resealable bags at karton.eu are available in an extensive range of standard sizes to meet diverse storage requirements. Popular formats include 150x220mm, 160x220mm, and 180x250mm, among many others. We stock over 2,000 different formats of zip lock bags, ranging from small sizes for jewelry and small components to large formats for bulky items and commercial applications. Whether you need compact LDPE bags for organizing small parts or larger poly bags with zipper for workshops and shipping, our comprehensive selection ensures you'll find the perfect size. All sizes are available immediately from stock with competitive wholesale pricing and free standard shipping throughout mainland Germany.

Question 4: Can I reuse LDPE zip lock bags for different purposes?
Yes, LDPE zip lock bags are designed to be durable and reusable for multiple applications. Our resealable plastic bags feature robust zipper closures that maintain their sealing quality even after repeated opening and closing. You can reuse these transparent zip bags for various purposes such as organizing workshop tools, storing office supplies, protecting items during shipping, or general household storage. The tear-resistant LDPE material ensures longevity, and the bags can be easily cleaned if used for non-hazardous materials. For hygienic reasons, we recommend using fresh bags for food storage rather than reusing bags that previously contained consumables. The 90 micron heavy-duty versions offer even greater reusability for demanding commercial applications.

Question 5: Do you offer bulk discounts for zip lock bags?
Yes, we offer competitive wholesale pricing and bulk discounts for zip lock bags at karton.eu. Business customers can order in bulk quantities of 1,000 pieces or more at significantly reduced prices, making our resealable bags extremely cost-effective for commercial applications. As a B2B partner since 2007, we provide attractive terms for large orders, including invoice payment options for registered business customers. Private customers also benefit from our tiered pricing structure when ordering larger quantities. All bulk orders are shipped directly from our warehouse with reliable EU-wide delivery and complimentary standard shipping throughout mainland Germany, ensuring your packaging supply chain remains uninterrupted.

Question 6: Are your zip lock bags food-grade and safe for freezer storage?
Yes, our food-grade zip lock bags are specifically manufactured for safe contact with consumables and are perfectly suitable for freezer storage. These LDPE resealable bags meet all regulatory requirements for food packaging and are free from harmful substances. The secure zipper closure creates an airtight seal that protects food from freezer burn, moisture loss, and odor transfer. Our transparent zip bags allow easy identification of contents without opening, and the durable material withstands freezer temperatures without becoming brittle. For optimal freezer performance, we recommend our 90 micron heavy-duty versions, which provide enhanced protection. All our PE resealable bags are 100% recyclable and manufactured from sustainable polyethylene.

Question 7: What are VCI zipper bags and when should I use them?
VCI zipper bags are specialized resealable bags with integrated Volatile Corrosion Inhibitor technology, designed to protect metal parts and components from rust and corrosion during storage and shipping. These reclosable bags release corrosion-inhibiting vapors that form a protective molecular layer on metal surfaces, preventing oxidation without leaving residue. VCI zipper bags are ideal for industries such as automotive, manufacturing, electronics, and metalworking, where ferrous and non-ferrous metal components require long-term protection. Unlike standard LDPE zip lock bags, VCI bags provide active corrosion prevention for up to 24 months. They are available immediately from stock at karton.eu with fast delivery for your industrial packaging needs.
