Pillow Pouch

Pillow Pouch

This frozen Xiao Long Bao back-seal bag is a composite flexible packaging product specifically designed for this emerging frozen pastry category. Xiao Long Bao are known for their paper-thin skin, only about 1mm thick, which becomes translucent and soft after steaming. Their thin skin and generous fillings place extremely high demands on the packaging's resistance to compression and damage. The back-seal bag (also known as a center-seal bag or pillow bag) has its seal located in the center of the back, with no obstruction on the front, allowing for complete display of brand information. This product uses low-temperature resistant composite materials to ensure the Xiao Long Bao will not crack or deform even at -18℃, fully meeting the protection and display needs throughout the entire supply chain from production to consumption.

Product Overview

Pillow-shaped bags, also known as back-seal bags, center-seal bags, or pillow-type bags, are flexible packaging products with a longitudinal seal on the back. The bag consists of three seams: top, bottom, and back, and its overall shape resembles a pillow, hence the name. Back-seal bags use a single longitudinal back seal plus a horizontal bottom seal, leaving the front completely unsealed, resulting in a smooth and aesthetically pleasing appearance. This type of bag offers high production efficiency and significant cost advantages, and is widely used in various food and non-food packaging applications.

Key Features

1.Complete and Aesthetically Pleasing Front Design: The seal of the back-seal bag is hidden on the back, with no obstructions on the front, maximizing the integrity of the front design. The design allows for a unified front image, maintaining continuity, resulting in a refined, aesthetically pleasing, and distinctive appearance.

2.Significant Cost Advantage: For packaging bags of the same size, the back-seal method minimizes the total seal length and reduces material consumption. Without affecting production speed, it can reduce packaging material usage by approximately 40%, resulting in a significant cost advantage.

3.High Production Efficiency: The back-seal bag manufacturing process is mature and suitable for high-volume, rapid production. Automated packaging equipment can switch between back-seal and three-side-seal bags through modular design, meeting the packaging needs of all channels.

4.Strength and Protection: The bags have stronger pressure resistance on both sides, greatly reducing the possibility of packaging damage. They also offer advantages such as moisture and water resistance, insect and pest protection, and prevention of product spillage.

5. Excellent display effect: The back-sealed bag has a full shape after packaging, which is especially suitable for inflatable packaging (such as nitrogen-filled potato chips), with outstanding visual effect and strong shelf appeal.

FAQ

Q: What is your MOQ for custom packaging?

A:

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?

A:

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?

A:

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?

A:

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?

A:

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?

A:

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.
