Exploring Each Layer

Outer Layer: PET/LLDPE

The outer layer, often made from PET or LLDPE, serves as the first line of defense. It’s where the magic of branding happens, with eye-catching designs and essential information being printed here. This layer ensures the pouch is tough enough to withstand external pressures.

Middle Layer: Aluminum Foil

The aluminum foil layer is a crucial component in maintaining the freshness and taste of the juice. Acting as a barrier against light and air, it keeps the contents as fresh as the day they were sealed.

Inner Layer: Food-Safe Plastics

The inner layer, in direct contact with the juice, is made from various plastics that are safe for food contact. This layer adds to the structural strength of the pouch, ensuring it maintains its shape and integrity.

Advanced Options: Co-Extruded Layers

Our advanced pouch designs sometimes incorporate co-extruded layers for added functionality like enhanced puncture resistance. These layers can be tailored to suit specific product needs, ensuring optimal performance and longevity.

The Making of a Pouch: Precision and Expertise in Every Step

Juice pouches are not just about their layers; it’s how these layers come together that counts. At ShenZhen YongLianTai(YLTpacking) Plastic Bag Co., Ltd., we follow a meticulous process to ensure every juice pouch we produce meets the highest standards of quality and functionality. Here’s a step-by-step look at how we create these everyday marvels:

Table: The Manufacturing Process of Juice Pouches

StepProcess DescriptionKey Importance
Film FormationCreating plastic and/or aluminum foil layersBase structure for pouches
PrintingAdding designs and brand information to outer layerBranding and consumer appeal
LaminationCombining layers into a single structureDurability and integrity
Pouch FormingShaping into the pouchPracticality and usability
Spout AttachmentAdding dispensing spoutConvenience and leak-proof functionality
Quality ControlEnsuring pouch integrity and safetyConsumer trust and product reliability

1. Film Formation

The journey begins with film formation. We use either blown film extrusion, cast film extrusion, or create laminated structures. This step is about laying the foundation – creating those individual layers that will later become a part of the juice pouch.

2. Printing

Next, we bring colors and life to the outer layer. Using state-of-the-art printing technology, we adorn the pouch with vibrant designs and important brand information. This is where our highly recommend strong liquid spout bags for juice get their distinctive look.

3. Lamination

In lamination, we fuse the layers into a single structure. This can be done with or without adhesive, depending on the required properties of the pouch. It’s a delicate balance to maintain the integrity of each layer while creating a cohesive whole.

4. Pouch Forming

The laminated material is then shaped into the familiar pouch form. This involves using heat and pressure to mold the material, ensuring the pouch is both practical and appealing.

5. Spout Attachment

A critical step in our process is the addition of the specialized dispensing spout. This not only adds convenience for the end-user but also ensures a secure and leak-proof seal. Check out our wholesale liquid stand-up nozzle pouch with spout to see this in action.

6. Quality Control

Finally, every step of the process is accompanied by rigorous quality control. We ensure that each pouch maintains its integrity and is safe for food contact, securing consumer trust and product reliability.
