Rollstock Film

Product Overview

Roll film can be understood as "finished bags that have not yet been cut and sealed." It is a roll of flexible packaging material, a core intermediate product connecting packaging and printing plants with automated production lines. Simply put, the bag is the final form of the roll film, while the roll film is the "semi-finished" state of the bag. Multi-layer composite roll film is a type of roll-shaped flexible packaging material made by bonding two or more layers of films of different materials through processes such as dry lamination, solvent-free lamination, or extrusion lamination. Unlike traditional single-layer films or pre-made packaging bags, it is supplied to customers in roll form, working with automated packaging machines to complete online bag making, filling, and sealing in an integrated production process. Composite packaging roll film features high strength, aesthetic appeal, controllable cost, and ease of use, and has been widely used in automated packaging in the food and pharmaceutical industries in developed countries such as Europe, America, and Japan.

Key Features

1. Suitable for High-Speed Automated Production: Roll film is specifically designed for automated packaging machines, enabling full automation of bag making, metering, filling, sealing, and cutting. This significantly improves production efficiency and reduces labor costs, making it an ideal choice for large-scale production.

2. Complementary Material Properties, Integrated Functions: Integrating the advantages of different materials creates a comprehensive protective capability that a single material cannot achieve. For example:

* Outer Layer: Provides mechanical strength and printability

* Middle Barrier Layer: Provides oxygen, moisture, and light protection

* Inner Layer: Provides heat-sealing for food safety

3. Superior Protective Performance: The multi-layered composite structure endows roll film with excellent oxygen barrier, moisture protection, light protection, puncture resistance, and good heat-sealing properties.

4. Exquisite Printing, Excellent Brand Display: Capable of gravure multi-color printing, producing exquisite prints with high color saturation, effectively showcasing brand image and product information. Some products can also feature an easy-tear line design to ensure easy tearing while maintaining airtightness.

FAQ

Q: What is your MOQ for custom packaging?

Our minimum order quantity (MOQ) varies by product type and complexity. For standard stand-up pouches and flat bags, MOQ starts at 5,000 pieces. More complex shapes or custom tooling may require higher quantities-typically 10,000+ pieces. We recommend discussing your specific requirements with our team to find the most cost-effective solution for your volume needs.

Q: What printing methods do you support?

We offer two primary printing methods: Gravure printing and Digital printing. Gravure printing utilizes etched cylinders for up to 10 colors, delivering exceptional print quality and cost-effectiveness for large runs of 10,000+ units. Digital Printing offers flexibility with no color limitations, ideal for smaller quantities, customizations, and rapid prototyping. Both methods achieve vibrant, high-resolution results suitable for food-grade applications.

Q: What materials are available for food packaging?

We provide an extensive range of food-safe materials including: PE (polyethylene) for basic applications, PP (polypropylene) for higher temperature resistance, PET (polyester) for clarity and durability, metallized films for premium barrier properties, aluminum foil for maximum oxygen and light protection, and specialty recyclable and biodegradable options. Our team can recommend optimal material structures based on your product specific preservation requirements.

Q: Can you provide samples before production?

Yes, we strongly recommend samples before mass production. We offer prototype sampling services typically taking 7-10 days. Samples allow you to evaluate material quality, print accuracy, functional features, and overall appearance. For complex custom orders, we provide pre-production samples for your approval before commencing full production runs, ensuring complete satisfaction with the final product.

Q: What certifications do you have?

Ente Packaging maintains comprehensive certifications including: ISO 9001:2015 for quality management systems, BRC (British Retail Consortium) certification for food safety, FDA registration for food-contact materials, EU regulation compliance for European markets, and SEDEX certification for ethical supply chain practices. We also hold FSSC 22000 food safety certification and can provide relevant documentation for customs clearance and compliance requirements.

Q: How long is the production lead time?

Production lead times depend on order complexity and quantity. For standard orders with MOQ (5,000-10,000 pieces), typical lead time is 15-20 days from sample approval. Orders requiring custom tooling or complex specifications may take 20-30 days. Express production is available for urgent requirements with additional fees. We provide detailed production schedules during the quotation phase and keep you informed throughout manufacturing.
