a roll of biaxially-oriented, reflective and transparent foil in which a flame retardant is at least partially dissolved therein, the foil exhibiting a haze of less than 10%; and
an anti-stick filler added during a foil extrusion process such that the anti-stick filler reduces a tendency of adjacent foil surfaces from sticking to one another.
15. The system of claim 14, wherein the foil exhibits a haze of less than 5%.
16. The system of claim 14, wherein the flame retardant is fully dissolved therein.
17. The system of claim 14, wherein the foil further comprises an anti-reflective coating.

The claims below are in addition to those above.
All refrences to claims which appear below refer to the numbering after this setence.
1. A serial bus device for transmitting a packet to a link partner, comprising:
a processing unit, generating the packet; and
a clock difference compensation unit coupled to the processing unit, determining whether to transmit at least one skip ordered set to the link partner prior to the packet according to a type of the packet, so as to compensate for a clock difference for the link partner.
2. The serial bus device as claimed in claim 1, wherein the clock difference compensation unit comprises:
a skip symbol generator, generating the skip ordered set which comprises two skip symbols; and
an arbitrator coupled between the processing unit and the skip symbol generator, determining whether to transmit the skip ordered set to the link partner prior to the packet according to the type of the packet.
3. The serial bus device as claimed in claim 2, wherein the arbitrator identifies the type of the packet according to a type field within a header of the packet.
4. The serial bus device as claimed in claim 2, wherein the arbitrator determines whether to transmit the skip ordered set to the link partner prior to the packet according to a data length of the packet when the packet is a data packet.
5. The serial bus device as claimed in claim 2, wherein the arbitrator directly transmits the packet to the link partner when the packet is not a data packet.
6. The serial bus device as claimed in claim 4, wherein the arbitrator transmits the skip ordered set to the link partner prior to the packet when the packet is the data packet and the data length of the packet is larger than or equal to a specific value.
7. The serial bus device as claimed in claim 6, wherein the arbitrator directly transmits the packet to the link partner when the packet is the data packet and the data length of the packet is smaller than the specific value.
8. The serial bus device as claimed in claim 4, wherein the arbitrator obtains the data length of the packet according to a data length field within a header of the packet.
9. The serial bus device as claimed in claim 4, wherein the arbitrator controls the skip symbol generator to generate the skip ordered set when the packet is the data packet and the data length of the packet is larger than or equal to a specific value, and a quantity of the skip ordered set generated by the skip symbol generator corresponds to the data length of the packet.
10. A clock difference compensation method for a serial bus device, comprising:
determining whether a packet to be transmitted to a link partner is a data packet; and
transmitting at least one skip ordered set to the link partner prior to the packet when the packet is the data packet and a data length of the packet is larger than or equal to a specific value, so as to compensate for a clock difference between the serial bus device and the link partner.
11. The clock difference compensation method as claimed in claim 10, further comprising:
directly transmitting the packet to the link partner when the packet is not the data packet.
12. The clock difference compensation method as claimed in claim 10, further comprising:
directly transmitting the packet to the link partner when the packet is the data packet and the data length of the packet is smaller than the specific value.
