Polymeric films underpin modern packaging by combining lightweight protection with high-throughput manufacturability (blown film, cast film, BOPP/BOPE, BOPET). Typical applications include:
-
Food & beverage: primary wraps, lidding, pouches, MAP/Vacuum packs, shrink and stretch films
-
Personal care & household: sachets, refill pouches, diaper backsheets
-
Industrial & logistics: stretch wrap, protective films, heavy-duty sacks, liners
-
Agriculture: mulch and greenhouse films
COMMON POLYMERS
-
LDPE / LLDPE: sealability, toughness, puncture resistance; prime layers for pouches and liners
-
HDPE: stiffness, moisture barrier; grocery and heavy-duty bags
-
PP (homo-/random, BOPP): clarity, gloss, heat resistance; labels, snack wraps, overwraps
-
PET (BOPET): dimensional stability, high heat resistance, print receptivity; metallized barrier webs
-
PA (Nylon): abrasion and puncture resistance; retortable and vacuum structures
-
EVOH / PVDC (barrier layers): oxygen barrier for aroma and shelf-life extension
-
PS / EPS: thermoformable trays and lids
-
Biopolymers (PLA, PBS, PHA): compostable or bio-based options for selected formats
BENEFITS
-
Lightweighting and reduced transport emissions
-
Tailored barriers (O₂/CO₂/H₂O/aroma) via mono- and multilayer design
-
Process efficiency: high line speeds, low energy per pack, consistent sealing windows
-
Mechanical performance: impact, puncture, and tear balance tuned by resin and orientation
-
Optics & branding: clarity, gloss/matte control, printability, and surface treatments
-
Functionality via additives: UV stabilization, slip/antiblock, antistatic, antifog, antimicrobial
-
Regulatory readiness: food-contact-compliant grades available; growing pathways to recyclability (PE-PE, PP-PP mono-materials)
