What Packaging Leaders Say
About Celesta Exim Solutions

Read verified statements from procurement directors, production managers, and brand leaders who rely on our barrier laminations and cylinder printing fidelity.

“Celesta Exim resolved our recurring seal-leakage issues on high-speed VFFS lines. The low COF and consistent hot-tack strength allowed our packing lines to increase output from 65 to 80 packs per minute without bursting. Their cylinder registration and print sharpness on 3-ply metallized laminate remain exceptionally consistent across repeat runs.”
Application: 3-Ply PET / MET-PET / PE Rollstock for Nitrogen-Flushed Snacks
“Switching from rigid glass jars to Celesta's spouted stand-up pouches cut our primary freight shipping weight significantly while totally eliminating transport breakage. The corner fitments are hermetically welded and endure 1.5-meter drop impact tests with zero failures.”
Application: Nylon (PA) / PE Spouted Pouches with Tamper-Evident Closures
“The registered soft-touch matte finish and spot-gloss typography produced on Celesta's 8-color rotogravure press gave our coffee bags top-tier shelf prominence. The one-way degassing valves function flawlessly, releasing CO2 without letting any oxygen into the beans.”
Application: Matte-BOPP / Foil / PE Flat-Bottom Box Pouches with Valve
“Packaging hybrid seeds requires hermetic moisture exclusion and puncture resistance against sharp seed husk corners. Celesta supplied heavy-duty co-extruded barrier structures that passed our automated drop tests with zero bursting or delamination.”
Application: 5-Layer Co-Ex Heavy-Duty Gusseted Bags for 5kg Hybrid Seeds
“Their technical polymer team visited our plant to evaluate our flow-wrap jaws. They fine-tuned the slip additive package on the rolls, enabling clean knife cutting and eliminating static clinging. Startup scrap dropped from nearly 9% down to under 2.5%.”
Application: BOPP / Pearlized-BOPP Continuous Flow-Wrap Rollstock

Savory snacks export shelf life and moisture barrier case study Snack Foods Export
Sector: Savory Namkeen & Chips Exporter Project Scope: Rollstock Reformulation

Resolving Transit Moisture Degradation & Seal Leaks for Middle East Export

Customer Challenge:

A regional snack brand suffered a 3.8% return rate during 35-day maritime export transit due to micro-pinholes in their standard 2-ply film, resulting in stale namkeen and nitrogen gas leakage.

Scope & Engineering Solution:

Celesta engineered an ultra-high barrier 3-ply structure (PET / Vacuum-MET-PET / Linear Metallocene PE) with calibrated slip additives and high hot-tack seal initiation for vertical form-fill-seal machines.

Measurable Outcome & Evidence:
< 0.02% Pinhole Leak Rate (down from 3.8%)
9 Months Crispness Guarantee Verified
Zero Transit Rejections in 14 Shipments
Spice aroma preservation and foil delamination prevention case study Spices & Essential Oils
Sector: Export Spice & Seasoning Mill Project Scope: Pure Aluminum Foil Pouches

Preventing Foil Delamination & Volatile Oil Migration in Ground Masalas

Customer Challenge:

Aggressive essential oils (eugenol in cloves and piperine in pepper) dissolved standard laminating adhesives, separating the aluminum foil from the polyethylene sealant layer within 40 days of packaging.

Scope & Engineering Solution:

Celesta deployed a specialized chemical-resistant solventless polyurethane adhesive formulation combined with an organoleptic non-migrating inner PE layer certified for direct spice contact.

Measurable Outcome & Evidence:
100% Bond Strength Retention at 50°C
Zero Foil Layer Separation or Delamination
100% Retained Aroma & Volatile Essential Oils
High speed flow wrap scrap reduction and COF calibration case study Bakery & Confectionery
Sector: High-Volume Biscuit Co-Packer Project Scope: HFFS Flow-Wrap Calibration

Reducing Startup Roll Scrap & Accelerating Machine Speed on Flow-Wrap Lines

Customer Challenge:

A biscuit packaging line running horizontal flow-wrap (HFFS) machines suffered excessive film web drag, jaw jam-ups, and a 8.5% startup scrap rate on every roll changeover.

Scope & Engineering Solution:

Celesta modified the extrusion slip additive concentration to maintain a strict 0.22 Coefficient of Friction (COF) and reduced seal initiation temperature (SIT) to 105°C for rapid fin sealing.

Measurable Outcome & Evidence:
1.8% Roll Startup Scrap (down from 8.5%)
+18 packs/min Packaging Line Speed Increase
12% Savings Annualized Packaging Film Material Cost
