Related information about spout bags

Spout bags replace hard packaging and are liquid packaging with mouths in the form of flexible packaging. The structure of the spout bag is mainly divided into two parts - the spout and the stand-up bag. The stand-up bag part is made of multi-layer composite plastic material to meet different food packaging needs. Performance and barrier requirements. The nozzle part can be regarded as installing a straw on the mouth of a general bottle and turning the lid. The two parts are tightly combined through heat sealing (PE or PP) to form liquid packaging for extrusion, suction, pouring or squeezing. It is an ideal new liquid packaging, so let’s learn about the comprehensive guide to spout bag packaging!

The advantage of spout bags over general packaging forms is portability. Spout bags can also be simply put into backpacks and pockets. As the content is reduced, the volume can become smaller and easier to carry. The main forms of soft drink packaging on the market are PET bottles, composite aluminum paper bags, and cans. In today's increasingly homogeneous competition, the improvement of packaging is undoubtedly one of the powerful means of differentiated competition.

Why should spout bags be packaged instead of hard packages? Bags are more popular than hard packages for the following reasons:

Low transportation costs - nozzle bags are smaller and easier to transport than hard packaging, reducing transportation costs;

Environmentally friendly because they are lightweight - spout bags use 60% less plastic than rigid packaging;

More than 98% of all contents taken out from a nozzle bag with less content waste is higher than that of rigid packaging;

Novelty – the spout pocket makes your product stand out on display;

Even better – the spout bag has enough surface area to design and promote brand identity;

Lower carbon emissions - the manufacturing process of the nozzle bag consumes less energy, is more environmentally friendly, and emits less carbon dioxide;

Spout bags have many benefits for both manufacturers and retailers:

The rotating cap of the nozzle bag can be resealable, suitable for consumers to reuse multiple times over a long period of time;

The portability of the spout bag makes it easy to carry and consume;

Spout bags are easier to use than ordinary flexible packaging and less likely to leak;

The mouthpiece bag is safe for children and has an anti-swallowing and suffocating mouthpiece, making it safe for children and pets;

Richer packaging designs are more attractive to consumers and stimulate repurchase rates;

Make single-material spout bags sustainable and in line with the 2025 environmentally friendly classified recycling packaging requirements and carbon neutrality emission reduction goals;

Why do the contents of high-temperature sterilization nozzle bags not need preservatives?

The retort bag is a composite plastic bag that can be sterilized by high temperature heating (121-125). It is currently mainly based on the high melting point of polypropylene PP heat sealing material and its safe and stable food packaging performance, aluminum foil, high barrier transparent nylon PA, high Blocks high burrs such as transparent polyester PET. Therefore, it is also called "soft can".

The retort bag has the application of all materials of the retort bag, and cooperates with the high-density PP retort bag to achieve high-temperature sterilization of liquid packaging. By using a pressure cooker at a high temperature of 121-125 for 20-40 minutes for pressure sterilization, 100% of bacteria, more than 99.99% of fungi and fungal spores, viruses and their nucleic acid proteins in the contents and packaging can be effectively killed; combined with high-barrier materials (high Barrier to oxygen and water vapor) to form a highly airtight container, achieving a shelf life of 12-24 months at room temperature in a sterile environment with highly stable content storage conditions (depending on sterilization conditions, storage conditions, and the performance of the barrier material).

The above is a comprehensive guide to spout bag packaging. In the past, most rigid packaging used antioxidants, stabilizers, food additives (preservative categories), etc. as added ingredients because most of them could not achieve high-temperature sterilization, high-oxygen barrier and other conditions. The high-temperature cooking and sterilizing nozzle bag can truly add zero additions, and the original product ensures a healthier and safer consumption concept.
