Highly filled Multibatches are used in many different processes and bring different benefit to the packaging manufacturer:

1. Blown film: they are mainly used as anti blocking masterbatches. Here are the main products and key properties.
   
   

   Product reference	Polymer carrier	Mineral filler	Concentration	Key properties
   ME 50003	LDPE	CaCO3	70%	Antiblock and antislip for heavy duty bags. Recommended for films thicker than 80µm
   ME 50004	LDPE	CaCO3	70%	Antiblock for opaque film thicker than 25 µm
   ME 50009	LDPE	CaCO3	70%	Antiblock for opaque film thinner than 25 µm
   ME 50024	LDPE	MgOH silicate	70%	Antiblock for transparent film and shrink covers
   LDPE 1520 CHA 17715	LDPE	MgOH silicate	15%	Antiblock for very transparent shrink wrap films
   MEL 3010 TKE	LLDPE	MgOH silicate	30%	Antiblock for very transparent shrink wrap films
   ME 50043	LLDPE	CaCO3 + TiO2	70%	Antiblock for white opaque film
   ME 50055	LLDPE	TiO2	70%	White masterbatch.

   
   
   
2. BOPP film: they are mainly used in BOPP film in order to reduce the film SG and offer a very good compromise SG, opacity and Gloss. Most common dilution ratio is between 8-12% in core layer .¹
   
   

   Product reference	Polymer	Filler	Filler content	Key properties
   MP 52206	PPH	CaCO3	70%	Low specific gravity (S.G.=0.6), low MFI
   MP 52253	PPH	CaCO3	70%	Low specific gravity (S.G.=0.6), high gloss
   MP 52355	PPH	CaCO3	70%	S.G.=0.65, higher opacity without TiO2
   MP 52632	PPH	TiO2	50%	White BOPP film
   MP 52518	PPH	40% CaCO3, 30% TiO2	70%	White opaque BOPP, S.G.=0.70
   MP 52720	PPH	60% CaCO3, 12% TiO2	72%	White opaque BOPP film, S.G.=0.68
   MP 52711	PPH	70% CaCO3, 5% TiO2	75%	White opaque film, S.G.=0.65

   ¹ The S.G. values given here are only indicative as the processing conditions and dilution ratio also strongly influence the results.

   
   
   
3. Sheet extrusion for thermoforming: In this business, MgOH silicates are necessary to reduce the cooling time, thus throughput, give a better thickness distribution while thermoforming and better heat resistance allowing their use in microwave oven.
   
   

   Product	Polymer	Filler	Filler content	Key properties
   MP 52211	PPH	MgOH silicate, CaCO3	70%	Good balance stiffness impact properties
   MP 52659	PPH	MgOH silicate	60%	High thermal resistance, compatible with acid food

   
   
   
4. Corrugated sheet: The same grades are used as in Sheet extrusion for thermoforming.
   
   
5. Melt coating: Those masterbatches and compounds lead to very good peel properties in aluminium coating
   
   

   Product	Polymer	Filler	Filler content	Key properties
   MP 52659	PPH	MgOH silicate	60%	Recommended for co extrusion of blown PPH films laminates
   MEL 3010 TKE	LLDPE	MgOH silicate	30%	Dedicated to Aluminium melt coating

   
   
   
6. Injection moulding: The mineral filled masterbatches are mainly used to reduce shrinkage, distortion, cycle time and improve stiffness and thermal properties of moulded polyolefin parts. We have some products dedicated to this process.
   
   

   Product	Polymer	Filler	Filler content	Key properties
   MP 52255	PPH	CaCO3	70%	Standard
   MP 52214	PPH	CaCO3	75%	High gloss
   MP 52659	PPH	MgOH silicate	60%	High stiffness
   MP 53857	PPC	MgOH silicate	60%	Better impact resistance
   MP 52211	PPH	MgOH silicate, CaCO3	70%	Good balance impact stiffness
