Octagonal Sealed Bag

This aluminum foil eight-side seal bag is a high-end composite flexible packaging designed specifically for powder products such as protein powder, meal replacement powder, coffee powder, and probiotic powder. Also known as a flat-bottom bag or square-bottom bag, it gets its name from the eight heat-sealed edges on the bottom and sides. It is formed in a single hot-pressing process using a special mold, creating a square and full rectangular structure. Aluminum foil is the core material, giving the packaging 100% light-blocking and ultra-high barrier properties, providing top-level protection for powder products sensitive to humidity, oxygen, and light.

Key Features

1. Exquisite Three-Dimensional Design and High-End Texture: The eight-side seal bag unfolds into a square and full rectangular shape, offering a strong three-dimensional effect and a high-end, sophisticated visual appeal. This feature makes it highly recognizable on shelves, quickly attracting consumers' attention.

2. Stable Standing and Excellent Shelf Display: The bottom is completely flat, unlike the curved or wrinkled bottoms of traditional stand-up pouches. The eight-side seal bag stands firmly on shelves without any auxiliary support.

3. Five-Sided Display and High Information Capacity: The eight-side seal bag has five display sides (front, back, left, right, and bottom), far exceeding the limitation of ordinary stand-up pouches with only two. It can fully showcase brand image, product information, multilingual instructions, etc., making it especially suitable for global sales and promotion.

4. Superior Sealing and Protection: The eight-side seal structure provides stronger sealing performance, effectively preventing leakage of contents and the intrusion of external air and moisture. The use of multi-layer composite materials enhances the bag's abrasion resistance and moisture resistance.

5. Excellent Load-Bearing and Stacking Stability: The eight seals work together to distribute pressure, resulting in a stable structure and stronger load-bearing capacity. The square shape facilitates neat stacking during warehousing and transportation.

6. Resealable and convenient to use: Eight-side seal bags are usually equipped with reusable zippers or chain straps, making it easy for consumers to open and reseal the packaging.

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.

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.
