Quam ut solvere problema "transferre metallis layer"?

Per "transfer" est Metallized film Est quod cum metallis film est nudatum inter stratis, magis de metallis amet transfertur aliis films. Causes the peel strength to decline,so that the performance of the product resistance to the content of the decline,affecting the quality of the product,this is a lot of compound flexible packaging factory,home often encountered the phenomenon,is also more difficult to solve the problem.At present,the more widely used aluminum plating films are VMCPP and VMPET,and the corresponding composite membrane structures are 0PP/VMCPP,PET/VMCPP, 0PP/VMPET,PET/VMPET and so on.In practical application,PET/VMCPP produces more transfer phenomenon.This is because PET itself has a certain polarity,combined with the outer electrons of aluminum atoms,forming electron cloud superposition,so that the fastness between them is strong - some: at the same time,0PP is non-polar material,and Et adhaesionem est pauper, plerumque in 2.0n / 15mm infra, ut pet. In addition, in processus of metallized amet productio, et layer de connectens materia est iactaret in film ad augendae ad vinculum vires inter aluminium et in film.The qualitas huius iacuit de coating et quoque related ad translationem gradum in metallis iacuit.

In addition ad qualis factors of metallized amet ipsum, sunt etiam qualitas factores of adhaesive.ordinary tenaces coating perficientur est pauper: et solvendo release est pauper, in ineunte, et ad penetrare in aluminium layer, et layer aluminium layer.

Ut ad fundamentaliter solvere problema de "translatio" de aluminium plating layer, ut observandum ad haec puncta in operatione compositum processus:

I. Ensure qualis est Aluminium Planta Film ipsum, quod est requirere solvere aliis difficults.if qualis est metallis amet ipsum pauper est, tunc utcumque boni compositum processus et melius tenaces est.

II. Elige ius tenaces, hoc est magis efficaciora via solvere translationem aluminium plating layer.in compositum aluminium philosophiam, in tenaces cum leviter maius perficientur sit elenens.adesives cum leviter pondus, quamvis melius coating et fortes intermisso, quamvis melioris et in tenuibus, sed fortes, quamvis melioris, sed fortes, quamvis et in aluminium, sed fortes actum, quamvis melioris et fortes, quamvis et in tenuissimo, sed fortes et in tenuissimo, sed fortes actum, quamvis meliori et fortes, quamvis et in tenuissimo, sed fortes, quamvis et in tenuissimo, sed fortes actum, quamvis meliori et fortes, quamvis et in tenuissimo, sed fortis et in tenuissimo, sed fortes, quamvis melius, sed fortes, quamvis et in tenuissimo, sed fortes, quamvis et in tenuissimo, sed fortes et damnum, quamvis magis et tenuissimo the coating.Do not choose large molecular weight,uneven molecular weight distribution and poor solvent release of adhesive,because the penetration of the solvent itself is strong,damage to the coating,but also affect the bonding strength: at the same time,the large molecular weight of adhesive in the production process,its molecular weight is also bound to be uneven.

3. Increase the softness of the film.In the preparation of glue,the dosage of curing agent is appropriately reduced,so that the degree of cross linking reaction between the main agent and curing agent is reduced,so as to reduce the brittleness of the film,so that it keeps good flexibility and extensibility,which is conducive to the control of the transfer between the aluminum plating layer. Simul cum coating quantum ad cortices vires productum, nimium aut parum erit afficiunt quale productum, parum, erit parva compositis fastiditate, facile ad excorio; nimium et auget sumptus. Simul moles coating completum curandum tempore diu tenaces moleculis facultatem moveri damnum coating.

4.Reduce the curing time.In principle,the curing temperature of ordinary film is generally controlled at 45- 50℃,and the composite products of plated saw film should in principle improve the curing temperature,using high temperature short-time curing way,the general curing temperature is between 50-60℃,do not low temperature for a long time or natural curing.
