PBL FILM WITH EVOH introduces an EVOH barrier layer into the standard PBL multilayer structure. Through a precise interlayer lamination process, the EVOH is stably embedded within the structure, not simply added as an extra layer.
This improves the barrier properties against oxygen and odors without significantly increasing costs.
Compared to ordinary PBL, it is more suitable for tube products where the color, odor, and active ingredients of the contents are critical; it is also more cost-effective, offers better printing performance, and is more compatible with tube manufacturing processes.
Product Advantages
PBL FILM WITH EVOH can slow down oxygen penetration, reduce the risk of oxidation of the contents, delay the loss of aroma or the intrusion of external odors, resulting in greater stability during the shelf life and reducing complaints and returns due to quality changes.
We have designed a balanced approach regarding the thickness and position of the EVOH layer, not pursuing extreme barrier properties, which ensures production stability and heat sealing success rate. The tube manufacturing process is smoother, suitable for long-term mass production, avoiding the situation where it performs well in the lab but fails in mass production.
Differences from standard PBL/ABL
Compared to standard PBL
Significantly improved barrier performance
More suitable for functional, non-basic products
Compared to ABL
Lower cost pressure
More flexible printing options
More suitable for multi-SKU, fast-iterating product lines
Product Manufacturing Process
EVOH Barrier Layer Position Control
PBL FILM WITH EVOH is not simply about increasing the EVOH thickness. Based on the requirements of tube forming and sealing, the optimal position of the EVOH layer in the structure is determined in advance to prevent poor sealing or tube defects caused by an inappropriate position.
Tension and Temperature Management During Multilayer Lamination
During the lamination stage, the tension and heat lamination temperature of each film layer are independently controlled to prevent the EVOH layer from overheating and affecting barrier stability.
Interlayer Bonding Strength Testing
Each batch of PBL FILM WITH EVOH undergoes random sampling and testing of interlayer bonding stability before shipment to ensure that the film material does not suffer structural damage during winding, transportation, and tube manufacturing.
Batch Sample Retention and Parameter Recording
Samples and key process parameters are retained for each order batch for subsequent replenishment and comparison, preventing inconsistencies after initial successful use.
Packaging and Shipping
The product is rolled according to order specifications, avoiding mixing different specifications.
Basic protective treatment is applied at the factory, making it suitable for long-distance transportation.
The outer packaging clearly indicates specifications and batch numbers for easy warehouse management.
Full container load or less than container load shipments can be arranged according to the customer's delivery schedule.
Upon receipt, the product can be used directly without requiring any further sorting or preparation.
After-Sales Service
In case of abnormalities during the usage phase, the issue can be traced back to the specific production batch.
Technical personnel will assist in determining whether the problem is related to materials or process compatibility.
Long-term cooperation projects support the locking of structural and printing solutions.
Important customers are supported with safety stock and replenishment schedule planning.
Why Choose Us
BoZhi doesn't just sell products; we understand how to use them effectively. Many problems aren't inherent to the materials themselves, but rather arise from a mismatch between the materials and the pipe manufacturing process. We get involved in projects from the early stages to help clients avoid these kinds of hidden risks.
We are better suited for long-term projects
Batch parameters are traceable
Long-term structural stability
We do not arbitrarily change formulations
We are willing to clearly explain any issues
We will directly inform you if a project is unsuitable, rather than accepting the order and then letting the customer discover the problems through trial and error.
