Custom Cigarette Packing Transparent BOPP Shrink Film With High Shrinkage
BOPP Oriented films can be used as heat-shrinkable films in shrink-wrap applications or can be heat set to provide dimensional stability. Heat sealing is difficult in BOPP films, but can be made easier by either coating the film after processing with a heat-sealable material (such as polyvinylidene chloride) or by coextrusion with one or more copolymers before processing to produce layers of film. Copolymers used in sealing layers must have high gloss and clarity and should have low sealing temperatures to prevent distortion of the oriented polymer during sealing. Random copolymers containing 3–7% ethylene are often used as sealing layers; the lower melting point (<132°C; <270°F) results in a 30% increase in line speeds, and they can be recycled with no significant loss of strength or clarity. Coating or coextrusion increases the barrier properties of BOPP film, decreasing its permeability to gases. Common barrier polymers are ethylene vinyl alcohol, polyvinylidene chloride, and polyamide; five or more layers may be coextruded or laminated, or the barrier polymer can be dispersed in the matrix polymer.

Shipping cost all about
It is deeply appreciated to take your kind pardon for any misunderstanding about the shipping price due to the package is shipped from China.
The contract we have stipulated with FedEx, DHL, UPS and EMS is already set and therefore all merchandise is sent via Air rather than Ground. While this may not be the most cost effective for all customers, in terms of delivery time, ease of shipment and reliability we have determined that this is the most effective overall.
The shipping cost for all merchandises are displayed by adding items to your shipping bag, you can estimate shipping time and cost and acquire more shipping cost information from our site.
International Shipping
International shipping costs are calculated in U.S. currency based on estimated shipment weight and destination. Shipping costs for orders placed on the website are fairly accurate, but there are times when those estimates are incorrect. If we need to adjust shipping charges for your order we will contact you to authorize those additional shipping charges.
