Solventless Laminating Machine for battery packaging

Stop Battery Film Defects on Your Solventless Laminating Machine

ByMr. Li

Lithium-ion battery pouch film, structurally composed of BOPA, aluminum foil, and CPP layers, requires extremely high manufacturing precision to ensure safety, chemical resistance, and structural integrity. Historically, dry lamination methods using solvent-based adhesives dominated this sector. However, environmental regulations and cost efficiencies have accelerated the adoption of the solventless laminating machine in flexible packaging and battery…

MonoMaterial Lamination

How to Master Tension Control for Monomaterial PE Film Lamination?

ByMr. Li

Converters switching to all-PE laminates for recyclability often run into the same problem: tension settings that worked fine for years on PET/PE structures start producing curling, uneven winding, or intermittent delamination once the structure changes to PE-PE. The film itself isn’t more difficult to work with. The issue is that most lamination equipment and operator…

Solventless Lamination Reduce PAA Risk

How to Reduce PAA Risk in Flexible Packaging Production?

ByMr. Li

PAA risk in flexible packaging is well documented where these compounds come from, why regulators treat them as a food safety priority, and which packaging structures are most vulnerable. What is less often addressed is the practical side: what does a converter actually need to change in their day-to-day production to keep PAA levels within compliant…

WVTR vs MVTR in Breathable Film Lamination

WVTR vs MVTR in Breathable Film Lamination – What’s the Difference?

ByMr. Li

Every week, we hear the same question from our quality control team or a confused customer: “Our breathable film spec sheet says WVTR, but our customer’s test report says MVTR. Are we talking about two different things?” Let me just clear this up for you right now so you can save time at your technical meetings:…

Laminate Breathable Films for Sanitary Products

How to Laminate Breathable Films for Sanitary Products?

ByMr. Li

The backsheet of a diaper or sanitary napkin is easy to overlook, it’s the layer nobody sees. But for manufacturers, it’s one of the most technically demanding components to produce. Getting it wrong affects everything: product comfort, regulatory compliance, and ultimately, whether a brand’s end users come back. Most hygiene backsheets are a laminate of two…

Bubbling in 3-Layer Lamination

Why Aluminum Foil Causes Bubbling in 3-Layer Lamination

ByMr. Li

Flexible packaging manufacturing presents several technical challenges when using a solventless lamination machine to implement a 3-layer lamination structure involving PET/AL/PE or BOPP/AL/PE material layers, like PET/AL/PE or BOPP/AL/PE, such as PET/AL/PE. Though solventless lamination eliminates organic solvents and reduces energy costs, without drying oven stages found in dry lamination, this requires exact mechanical control, chemical balancing, substrate…

PET AL PE Lamination principle

How to Reduce Waste in PET AL PE Lamination

ByMr. Li

As technical professionals working daily on the production floor of a pharmaceutical flexible packaging plant, our primary metric of success is operational efficiency combined with strict regulatory compliance. In the manufacturing of high-barrier materials, the PET AL PE triplex structure represents the industry standard for protecting sensitive solid dosage forms, powders, and liquids against oxygen, moisture, and…

BOPP PE 2-ply Lamination in Flexible Packaging

PET/PE vs. BOPP/PE 2-layer Lamination in Flexible Packaging: How to Choose

ByMr. Li

In the business of flexible packaging manufacturing, choosing the right substrate in 2-layer lamination technology is one of the most basic decisions that determines the shelf life of the package, the operability on equipment, and overall manufacturing cost. Being a technical professional at a packaging facility, I find myself often confronted with clients who have difficulty…

Solventless adhesive curing reaction curve

How to Cure Time in Solventless Lamination Adhesive via Precise Temperature Control

ByMr. Li

The efficiency and quality of flexible packaging production depend heavily on the chemical and physical performance of the materials used. This type of bond involves the use of solventless lamination adhesives. Solventless lamination process is the preferred method due to its environmentally friendly nature and convenience in that it does not require drying tunnels used by…
