Are There Frequent Complaints from Epoxy Glue Customers? It Might Be That The Packaging Materials Are to Blame! —— Three Common Problems and Professional Solutions

Your epoxy glue formula is excellent and the test results are outstanding. However, the market feedback always includes issues such as uneven distribution, poor glue flow, and poor curing? Don't rush to adjust the formula. The problem might likely lie in the last link of the supply chain - the packaging system. Let's help you investigate one by one and precisely solve the problem.

Problem 1: "The glue is always unevenly mixed, with some areas not drying properly or having insufficient strength."

Root cause analysis:
Mixer pipe mismatch: The length of the mixer pipe is insufficient or the design of the internal mixing elements is improper, preventing adequate mixing at the specified flow rate.

Drift in the output ratio of the rubber cylinder: The inner diameter of the rubber cylinder is incorrect or the piston of the rubber gun does not match, resulting in an imbalance in the proportion of A/B components being pushed out.

Our solution:
Carry out "formula-packaging material" linkage testing: Based on the properties of your glue, we will conduct a simulated gluing test. By cutting and observing the cross-section of the cured glue strip, we can visually verify the degree of uniform mixing.

Customized proportion compensation design: For special ratios (such as 10:1) or glue with extremely different viscosities, we can achieve physical compensation by customizing the inner diameter of the glue cylinder or the design of the mixing tube inlet, ensuring precise actual mixing ratios.

Problem 2: "The rubber cylinder leaks glue, cracks, or the glue gun is difficult to squeeze."

Root cause analysis:
Insufficient quality or craftsmanship of packaging materials: The sealing at the rubber cylinder interface is not tight, there are stress weaknesses on the cylinder body, or the material is too soft.

Back pressure of the mixing pipe is too high: A mixing pipe with an excessively dense mixing path was selected for a high-viscosity adhesive, resulting in extremely high construction resistance.

Our solution:
Strengthened material and craftsmanship: Utilize high impact copolymer material, optimize injection molding process, ensure uniform thickness of the cylinder body and secure sealing. Provide pressure resistance tests that exceed industry standards for guarantee.

Backpressure optimization service: We offer a variety of mixed plate combinations, which can provide a balanced solution of "efficient mixing and low construction resistance" for high-viscosity adhesives, thereby improving the user experience.

Problem 3: "The shelf life is short. The glue thickens or forms a crust within the container."
Root cause analysis: The barrier property of the packaging material is insufficient. Ordinary plastics have limited ability to block water vapor and oxygen. Over time, the performance of the glue (especially the components with strong water absorption) will deteriorate.

Our solution:
Recommended high-barrier solution: Offer multi-layer co-extruded plastic containers with an EVOH barrier layer, or recommend the aluminum film packaging solution. This will significantly extend the shelf life of the products, helping you enter the long-distance markets with stricter storage requirements.

Excellent packaging materials are the silent "quality representatives". We focus on solving these "invisible" problems of epoxy glue packaging materials. Through systematic analysis and customization, we help you reduce customer complaints, enhance brand reputation, and consolidate market trust. Let's start with the packaging materials and remove the last obstacle for your products.
